The Different Ways a Steel Structure Can Fail

The job of every structural engineer is to ensure any given building is safe and structurally sound. This can occur during the initial design of a building or during the inspection of an existing building. When it comes to steel structures, it’s hard to imagine them failing due to the strength of the building materials themselves. However, there are several different ways steel structures can fail, and most of them can be prevented with the help of great structural engineering practices. Here are the main ways steel structures can fail.

Insufficient Strength With Connections

Almost every time you hear about a steel structure failing, it’s because of a connection issue. A structural engineer has to put in an incredible amount of thought and detail when designing the joints and connections to ensure they are strong enough. Calculating the strength of joints and connections is a tedious process, and it’s important for the structural engineer and the construction professionals to be on the same page. Any type of miscommunication in the type of bolt or other materials to use can lead to insufficient strength and possible failure.

Tension Failures

Another possible failure in steel structures is putting too much tension on any given member. It takes a significant amount of tension to create this type of failure, and most of the time it only occurs when the structural engineer makes a mistake in the design process. Tension failures are widely known as the most dangerous type of failure, so every structural engineer places a high level of importance on it in the design phase.

Too Much Weight On Beams

Beams can fail in a steel structure as well. It’s fairly simple to figure out when this type of failure will occur, since it happens when the weight on the beams exceed the weight limit they can handle. Lateral torsional buckling is the main concern for every structural engineering company, since it involves predicting where the most significant amount of weight will be placed on the beam. The strongest point of the beam is in the center of it, so buckling could occur and lead to beam failure if the weight on either end of the beam is too much for it to handle.

BE Structural is a team of structural engineering professionals that has an extensive portfolio of construction and engineering projects. Whether a steel structure undergoes minor local buckling or has experienced significant structural failure, we have an expert ready to evaluate the situation and provide the best solutions. No project is too large, small or complex for our structural engineering professionals, so don’t hesitate to contact us at any time when you need us.

The Problems the Millennium Tower is Facing in San Francisco

When the $550 million construction for the Millennium Tower in San Francisco was announced, there were no shortage of buyers ready to spend millions of dollars to purchase living space. However, less than a decade later, those buyers have lost significant value in their investment due to various unforeseen issues to the tower.

Various structural engineering companies, as well as geotechnical companies, are evaluating the building daily to analyze the cracks, sinking and leaning that are clearly present. While the problems with the Millennium Tower are evident, there are still plenty of questions surrounding the safety of it, who is responsible for these issues and what structural engineering experts are going to do about it.

How Safe Is The Building Today?

The good news is the last time a structural engineer evaluated the building, it was deemed to be safe to live in, even if an earthquake occurred. However, the fact that the sinking of the building doesn’t appear to be slowing down anytime soon can’t be ignored. Structural engineering experts estimate the building will continue sinking between 1.5” to 2” every year, which simply means action needs to be taken now to prevent a potential disaster in the ensuing years.

Where The Blame Lies

Initial inspections indicate the main problem being in the foundation of the Millennium Tower. The soil it’s built on consists of sand, clay and mud, and the foundation does not even extend far enough down to reach solid bedrock. There’s some controversy surrounding the City of San Francisco and why they allowed the construction and design team to not anchor the foundation low enough to reach the bedrock.

Another area of blame has to do with the construction of the transit center that was newly built adjacent to the tower. The construction company responsible for building the Millennium Tower is suggesting the company that constructed the transit center pumped too much groundwater during their project, which caused the sand under the Millennium Tower to compress, and has resulted in the sinking.

Possible Solutions To Fix The Millennium Tower

As structural engineering experts continue to discover the reasons why the Millennium Tower is experiencing these problems, they are also developing short-term and long-term solutions. One of the possible solutions includes removing some of the top floors in order to reduce the weight of the tower. The most discussed solution for the long-term is to bore micro piles on the side of the building that’s sinking in order to eventually anchor it to the bedrock underneath. Once this occurs, the high side of the building must sink to the level of the low side before the anchoring can occur. This proposed solution could take up to five years and cost several hundred million dollars, but it is the most viable solution for the long-term, as analyzed by structural engineering experts.

At BE Structural, we always monitor these types of stories and are actually involved in many of them. We are a structural engineering company with experts coming from many different backgrounds and having various levels of experience.

What Qualities Should Your Structural Engineer Have?

When you have a new construction project or are doing major renovation work, one of the first experts to call is a structural engineer. However, just like not all structural engineering companies are created equally, neither are individual structural engineers. The best ones will work with the architects, designers and other contractors you hire in order to ensure everyone is on the same page with the same vision for the project. Before you hire a structural engineer for your project, make sure they possess these qualities.

Creativity

No two buildings are exactly alike, so your structural engineer should use their knowledge, skills and expertise to design the safest and strongest building for your particular project. This includes evaluating the weather and climate and using building materials that will withstand the harshest elements. Structural engineers have to be creative in order to build a safe structure, while still fulfilling the needs and vision of the homeowner or property owner.

Extreme Attention To Detail

There are plenty of obvious reasons why a structural engineer has to be extremely detailed in the work they do. One seemingly minor mistake could lead to a fatal flaw in the design of the building. And the structural engineer needs to follow through with the other contractors who are actually building the structure to ensure everyone is on the same page and there’s a complete understanding of their thought process.

Innovative Strategic Thinking

With the technology available to every structural engineering company today, there’s no excuse for not using innovative technology to help design a building. The challenge every structural engineer faces is being able to satisfy the needs and desires of the individuals, while also adhering to safety regulations, sustainability practices and more. It requires innovative and strategic thinking to be completely well-rounded, and taking the time to find a structural engineer who possesses these qualities is well worth the effort.

Problem Solving

Problems will always arise in any project, no matter how large or small it is. Whether it’s external factors like the weather, or other unique challenges that aren’t evident immediately, a good structural engineer must be able to think quickly. The best structural engineering professionals will be able to identify problems before they occur and plan on a solution, but sometimes it’s not possible. In either situation, coming up with the best solutions possible is an important quality for structural engineers to have.

5 Common Structural Issues in Industrial Buildings

The manufacturing industry is arguably the most important industry in the United States. While it’s important to keep manufacturing machinery and equipment maintained in order to keep production going, it’s equally as important to maintain the industrial buildings where the work is done. If the integrity and safety of an industrial building is compromised, it could lead to the manufacturing plant being shut down until a structural engineer can come in for an evaluation. While significant events like this are not likely with preventative maintenance practices, here are five of the most common structural issues in industrial buildings seen by structural engineering companies.

Interior and Exterior Wall Damage

Both interior and exterior walls will eventually experience some damage in industrial buildings. With forklifts, operations vehicles and other heavy equipment constantly being used, it’s inevitable for some damage to occur. The main thing to do is have a structural engineer evaluate the damage and have it repaired right away if necessary. Most of the damage is cosmetic, but it’s always better to be cautious.

Damage To Columns

Depending on how severe the damage is, a damaged column could be very dangerous from a structural standpoint. It seems like every column in an industrial building is in the way for forklift operators, which means they will get dinged up occasionally. But as long as the damage is minor and doesn’t have a structural impact, then operations can continue as normal.

Inadequate Framing

Many industrial buildings are very old. During the original design of the building, the framing was likely designed to support a certain amount of stress. When structural engineering experts see an issue with framing in an industrial building, most of the time it’s because too much stress was put on it. Because of this, it’s important for managers to have the framing inspected whenever additional equipment is added that could increase the stress on it.

Poor Roof Draining System

When water stays pooled on a roof without draining properly, there’s a wide range of issues that could occur. Any structural engineering company will inspect the roof of an industrial building to ensure gutters are working properly and the best systems are in place to properly drain water from the roof.

Neglected Maintenance Practices

Accidents will happen in an industrial building with so many moving parts at any given time. However, any structural engineer will tell you major issues can be prevented by performing routine maintenance practices. These could include ensuring roof drainage systems are functioning, no rust is present on steel components, all seals and connections are in good shape and more. If there are any issues that need the expertise of a structural engineer, don’t hesitate in contacting one.

BE Structural is here to ensure all industrial buildings are in good working order so manufacturing processes can continue without interruption. Production is critical for every manufacturing plant, but so is safety. As a structural engineering company, we will evaluate every component of your building, identify any potential issues and promptly fix them.

How Can Structural Engineers Build in a More Sustainable Way?

Waste is a common problem among many different industries worldwide, and the construction industry is one of the leaders in producing waste. However, with society becoming more aware and conscious of the materials they are using and how to properly dispose of them, structural engineering companies are also doing the same. This involves altering practices and procedures, disposing of waste differently, eliminating harmful compounds when using building materials and more. All of these combine to make more sustainable buildings and protect our planet as well. Here’s how structural engineering companies are building more sustainably today.

Incorporate Zero Waste Practices

Zero waste practices mean using products and materials that can be reused instead of discarded when they are no longer needed. A common example of this is when a structural engineer designs a building by using bolts for connections rather than welds. The bolts can be reused when the building gets remodeled or demolished, but anything welded will simply have to go to the landfill in most cases.

Eliminate Volatile Organic Compounds

Breathing in volatile organic compounds can be dangerous when ingested in large amounts. Building materials have traditionally contained these volatile organic compounds, but structural engineering companies are now being more conscious about the products and materials they use to ensure they don’t include them. Not only are these materials better for the environment, they also protect the construction workers who come in close contact with them.

Compost Waste Instead of Dumping in The Landfill

It’s easy for a structural engineer to say they’ll throw any waste in the landfill. However, many structural engineering companies today are composting some of their organic waste on the actual construction site when possible. This reduces the amount of waste in the landfills and also eliminates having to pollute the air with trucks driving to and from the landfills.

A Conscious Effort Will Go A Long Way

Being conscious of reducing waste and building in a more sustainable way will pay dividends for our environment in the future. The job of a structural engineer is to ensure a new project or a renovation project is designed in a safe manner, and also in a sustainable manner. Of course, it’s not always possible to apply all of these practices in every single construction product, but simply having sustainability in the back of the mind is a positive step forward for the environment.

BE Structural uses sustainable practices whenever possible. As a structural engineering company, it’s our job to ensure every building is designed and constructed safely. However, we are also very conscious of the environment we live in and the safety of the air we breathe. Quality does not have to be sacrificed when incorporating sustainable practices, so contact us today to see how we include these practices every day.

Will Building with Timber Ever Become the Norm?

A structural engineer is tasked with researching and analyzing the different materials that can be used to design and construct any given building. Some areas may need a steel or concrete building due to its climate or significant weather events, while others may be suitable for timber materials. There’s no doubting the possibility of using timber for nearly every project. However, the question many structural engineering experts have is whether building with timber will become the norm across the industry. Here’s a deeper look at this possibility.

Location Is A Major Factor

Since wood is weaker than steel or concrete, the location of a wood building is a critical component to think about. The reality is wood can be used in any location, but at what cost? Larger and thicker materials will need to be used in areas that experience significant weather events, which will increase the cost of the building and also potentially reduce the amount of living or working space due to the size of the materials. So in most of these situations, building with wood can be less economical in many ways.

Problems With Using Timber in Construction

In addition to the potential higher cost of using timber, structural engineering professionals also bring to light other possible problems. Shrinkage, creep, elastic deformation and similar issues all play a role in why a structural engineer may opt against using timber. The good news is most of the possible problems with using timber can be alleviated by combining other stronger materials with it, especially when you’re building taller structures.

Timber Combined With Other Materials is More Effective

Many structural engineering experts will suggest a hybrid construction for certain projects. Using steel or concrete for the structural aspects, and incorporating wood for columns and other aesthetic purposes, are typically the most effective strategies from structural and cost-effective standpoints. Every construction project is different, so each structural engineering company has to look at the unique aspects of the project to determine the sustainability of the materials used. Hybrid designs are quickly becoming the norm, so the likelihood of complete timber designs becoming standard is very low.

BE Structural is a team of structural engineering professionals dedicated to designing and constructing the most sustainable buildings for both commercial and residential purposes. Our structural engineering company provides services extending from the design and construction of a new project, to building renovations and even forensic analysis. We are experts in everything dealing with structural engineering, so contact us at any time and we would be proud to serve you.

How the Structural Engineering Industry is Changing with Technology

Technology impacts every industry in many different ways. As technological advancements continue to develop, structural engineering professionals always have to stay informed to ensure they are using the best practices. Whether it’s by incorporating more energy efficient materials or boosting productivity and efficient processes in the construction process, technology is typically beneficial for a structural engineer. Here are some of the main technological advancements used in structural engineering today.

The Use of Drones in Construction

Drones are used by structural engineering professionals to take aerial photos of a construction site, monitor activities and survey areas where accessibility is limited. The photos taken by drones have high resolution and can be used to take measurements, create digital models and much more. Plus, the use of drones is much safer for a structural engineer when it comes to surveying tall areas like roofs or bridges.

3D Printing

3D printing has significantly developed over the last several years. And in the coming years, it is expected to become an even more valuable resource for structural engineering professionals. Using 3D printing allows experts to create more accurate design details, as well as more customization for projects. 3D printing is typically used most effectively for commercial properties or in large-scale residential complexes.

Data Analysis Tools

There is a lot of data collected by a structural engineer before, during and after any construction project. Analyzing this substantial amount of data is important, but sometimes isn’t possible due to the sheer quantity. Data analysis tools continue to develop today to help structural engineering experts analyze the data collected most effectively. The technology, software and cloud solutions available today help gather significant amounts of data quickly and make it easily accessible to all members of the construction team to promote efficiency, accuracy and more.

Augmented and Virtual Reality

Augmented reality tools are typically used at the beginning stages of the design process. One of the main uses for these tools is to visualize how a particular construction design will fit in any given area. This allows structural engineers to identify any potential errors or complications and can fix them before the project even begins.

Virtual reality technology includes scanners and drones to collect information. This technology is helpful not only in the design process, but also to allow project managers to constantly monitor the progress of the project without having to be physically present. Accuracy and efficiency are the two main benefits of virtual reality tools and are increasing in importance every day.

BE Structural stays on top of the latest technological trends to ensure the most valuable resources are being used at all times. Any structural engineering company that doesn’t adopt the latest technology leaves room for critical errors which could be prevented.

What Materials are used in Sustainable Structural Engineering?

As people and companies become more conscious about energy consumption, perspectives in structural engineering are changing as well. It’s easy to upgrade appliances or install energy efficient equipment into new home designs, but those can get costly very quickly. The good news is there are sustainable materials used around the world today that are safe for the environment and can make very nice homes. Here are some of the materials a structural engineer will consider using when building a sustainable home.

Earth Bags

Earth bags are made of polypropylene material and are filled with soil and other inorganic materials. They are designed to hold up better than concrete or bricks, since the bags will not crack or be easily damaged during events like an earthquake. Earth bags are used prominently today in developing countries to build sustainable homes.

Earth Blocks

A structural engineering company will sometimes use earth blocks instead of bricks to create a more sustainable design. The earth blocks consist of a mix of clay, rubble and subsoil and are compressed at a very high pressure. In fact, earth blocks are actually stronger than concrete blocks or bricks, but only use a very small amount of cement. By using a small amount of cement, earth blocks are sustainable and reduce the amount of carbon emissions released into the atmosphere.

Retrofitting

Seismic retrofitting can be used to rebuild, repair or strengthen structures in general. After a structural engineer evaluates a building, they can perform actions such as repairing any damage, increasing shear wall density, strengthening ground conditions and more. Seismic retrofitting has helped strengthen thousands of buildings worldwide, especially in developing countries that experience earthquakes and other natural disasters.

Trombe Walls

Trombe walls are used in sustainable structural engineering to create more of a passive solar design in homes. The outside of the walls are made with plastic or glass panes, and the inside of the walls have a higher heat capacity. What makes these walls sustainable and energy efficient is the fact that the external wall will absorb the daytime heat and transfer the heat into the home when needed. Trombe walls are used effectively in areas where sunlight is present the majority of the time and people want to create a more sustainable and energy efficient design for their structure.

BE Structural is a team of experts with a wide range of experience. Our structural engineering company has worked with sustainable materials in different construction projects, and we always practice innovative thinking. It’s important to work with a qualified structural engineering professional if you’re considering using sustainable materials for your next construction project, so contact us to see how we can help you.

The Importance of Structural Engineering When Designing a Passive Solar Home

A passive solar home is unique due to the fact that essentially every element of the home is used to collect energy and distribute it evenly throughout the home. This includes the floors, roof, walls and even the windows. The only way these passive solar homes can be effective is by the careful and thorough design by a structural engineer. Everything from the area you build the home at, the materials, the base structure and more all combine to make a passive solar home useful. Here are some things to consider about structural engineering and passive solar homes.

Factors To Consider For Passive Solar Homes

The sun doesn’t have to shine around the clock in order for passive solar homes to work, but these factors are essential:

  • Location on the land you’re building on. By building the home on the northern side of the lot, the southern end of the home will have the clearest possible view of the sun.
  • The structure itself. Your structural engineer will tediously design the windows and walls to ensure they are exposed to as much sunlight as possible. Some windows should allow sunlight in, while other surfaces on the structure should absorb the heat to store and use at a later time.
  • Design materials. The most common materials used in passive solar homes include brick, tile, stone and concrete. These are the best thermal mass materials since they absorb and store heat from both the inside and the outside to be used at the appropriate times of the year.

Challenges When Designing Passive Solar Homes

From a structural engineering perspective, the main challenges of designing a passive solar home include ensuring the home is air tight and is structurally stable. Most passive solar homes will have a larger ratio of windows on the southern side of the building, which means there will be fewer structural shear walls on that side. In order to prevent damage to the windows because of the stress placed on them, trimming beams are usually specially designed to give them additional strength.

Collaboration And Comprehensive Analysis is Essential

A structural engineer must work closely with the design team and any other contractors who are working on a passive solar home. Since there are so many different nuances and various components to these homes, every detail is critical. Every good structural engineering company can take the lead in ensuring the home is designed and constructed safely and will be as effective as possible.
