3 Types of Failures in a Steel Structure

Steel structures are unique in both an appearance and construction aspect. Steel is an extremely strong material with many different levels of strengths and members that all have to be connected correctly in order to make a building structurally sound. Not all steel members are created equally with the same strength, so structural engineering professionals must test the strength of each member against the force put against it during construction. Not doing so can lead to structural failure, which can cause devastating consequences. Here are three of the most common types of failures in steel structures that every structural engineering company sees.

Beam Failure

Beam failure in steel structures doesn’t occur very often, but it is a legitimate concern every structural engineer has to be conscious of. This type of failure happens when a beam doesn’t flex properly or experiences something called lateral torsional buckling. Since pressure is typically not applied directly to the center of the beam during construction, twisting can occur. Failure typically happens when the beam is not braced with anything to support the twisting motion.

Tension Failure

Every structural engineer knows the risks and consequences of trying to stretch any given material too much. When designing any given member in tension, structural engineering professionals must be cautious of a possible net section rupture or block shear failure. These are two common failures directly related to tension, but typically do not occur when an experienced structural engineer works on the project.

Connection Failure

Connection failure is by far the most common type of failure in a steel structure. The connection is typically the first component to fail if the force of the load is more than anticipated. When a structural engineer designs the construction of a building, they use precise calculations to determine the strength of bolts or other connections needed. However, one minor miscalculation or a misstep in the construction process can lead to unpredicted force and failure at that particular connection. The challenge for every structural engineer is to take human error into consideration during the construction phase and design the connections to withstand a little more force than calculated.

How to Choose the Right Engineering Firm For Your Job

The success of any construction project can be greatly impacted by the structural engineering company you hire to do the analysis upfront. Every structural engineer has their own strengths, weaknesses and experiences, so finding the right fit for your particular project is important. You may have to spend some time and effort researching the best companies, but you’ll be rewarded in the end. Here are important things to consider when choosing the right structural engineering company.

Consider Qualifications Rather Than Cost

Choosing a structural engineering firm based solely on cost is one of the worst things to do. Instead, your decision should be based on their qualifications as it relates to your specific project. For example, consider the firm’s experience with other similar jobs, how available they are, their performance history, technical skills and certifications, values, timeliness and more. Your chances of being pleased with the entire process and end result will increase when these qualifications are given higher regard than the cost.

Ensure Compliance Codes Are Prioritized

The structural engineering company you ultimately hire should adhere to all compliance codes in your area. If they do not prioritize these compliance codes, you could be on the hook for fines and potential long-term issues. Be sure to have a serious and extensive discussion with the structural engineer from the firm you’re considering and get a comprehensive answer regarding how they adhere to compliance codes.

Evaluate Their Attitude and Behavior

You have to feel comfortable with the structural engineer in more ways than one. Since you’ll be collaborating with them extensively over the course of the project, evaluating their behavior and overall attitude is important. Make sure you are on the same page from the very beginning. When you get the sense the structural engineering firm has your best interests in mind, you’ll feel more comfortable moving forward with them.

Have A Structured Agreement In Place

No matter how much you trust the structural engineer, you have to have a structured written agreement in place to save yourself from potential issues in the future. Most large structural engineering companies will have these documents ready, but it’s also advisable to have your own legal counsel evaluate the agreement.

The Answers Behind the Miami Pedestrian Bridge Collapse

Back in March 2018, a pedestrian bridge under construction in Miami collapsed and killed six people. The project was designed to create a unique walkway to help students at Florida International University cross the highway safely. However, the unique design proved to be too difficult to accomplish and a fatal flaw in the construction process was never discovered. In the several months since the accident occurred, more answers have surfaced as structural engineering experts have been analyzing the situation and have contributed countless hours of investigative work.

What Caused The Bridge To Collapse?

Structural engineering experts have concluded that the complex structural design of the bridge left an obvious weakness at a connection point. This is most likely the reason why the bridge collapsed, since the amount of stress put on the concrete brace was too much for it to handle. As every structural engineer evaluates the situation, it’s becoming even clearer this was the problem that led to the devastating consequences.

The Bridge Was Not Structurally Sound or Logical

Prior to the pedestrian bridge collapsing, engineers noticed cracks in the concrete and became worried. Investigators believe the construction crew was working to tighten the steel rods in the support truss in order to address the cracks when the bridge collapsed. It’s possible the overtightening of the steel rods led to them snapping and causing the bridge to collapse under its own weight.

What’s being discussed at length is the design of the bridge itself. The unique design seemed like a good idea, but it’s clear it was a little too over-the-top for the structural engineering team working on it. Some of the findings by independent structural engineering firms have led to similar conclusions, which are that it’s inconclusive as to who is actually at fault. The atypical design of the bridge did not make it structurally sound, but the calculations and plans for the project did not clearly indicate what the root cause of the issue was.

The Role of Structural Engineers in The Investigation

Answers will still be coming over the course of several months or years, and structural engineering experts will be at the forefront of them. The role of a structural engineering company and its experts is to present the facts to the investigative team. As of now, it appears the structural design was the main cause for the bridge collapsing, but as further evidence is discovered by structural engineering experts, those answers could change.

The Effects of Wind and Hail on a Flat Roof

Wind and hail can cause significant damage to buildings, and especially those buildings with a flat roof. The majority of commercial buildings have flat roof systems and can all be constructed differently. The most common construction materials include multi-ply asphalt systems, single-ply membranes or metal panels. The role of a structural engineer when constructing a commercial building is to determine the best material to use to withstand the weather conditions most commonly seen in the area. Some of the most damaging weather comes from wind and hail, and here’s how those conditions impact a flat roof.

Vulnerable Areas of A Flat Roof

With a flat roofing system, the most vulnerable areas prone to wind damage are on the corners and around the edges of the roof. This is due to the uplift pressure of the wind, which can actually be much faster than the horizontal wind speed itself. The problem with these vulnerable areas is when the perimeter of the roof gets damaged, it can start peeling back and lift up. In worst case scenarios, the wind pressure can get under the roof and essentially blow it off of the building. However, these scenarios are very rare, since structural engineering professionals have strict codes and guidelines to follow to ensure it doesn’t happen.

Is Hail Damage Only Cosmetic?

The type of roof covering used on a flat roof makes a difference in whether hail damage is only cosmetic or can create larger issues. Hail as little as ½” in diameter can create dents in a metal roof. While most of this damage is cosmetic, the finish on the roof could be compromised, cause rust and shorten the lifespan of the roof. Single-ply roofs are more vulnerable to experiencing damage that’s more than cosmetic. It will still take hail of 1” in diameter or more to cause serious damage, but every structural engineer suggests inspecting the roof frequently and thoroughly to determine any vulnerabilities.

Frequent Roof Inspections Can Prevent Significant Damage

Any structural engineering company will highly recommend conducting roof inspections often. The age of the roof plays a big role in how vulnerable it is to wind or hail damage. Too many commercial properties make the mistake of not replacing their roof soon enough, since severe wind and hail events don’t happen every day. But with the unpredictability of the weather, it’s best to be prepared and have a structural engineering professional out to make a recommendation on how to protect the roof from damage.

The Advantages of a Modular Home

With custom underground homes becoming popular in many countries, modular homes are also getting more recognition. If you aren’t familiar with modular homes, they are constructed by assembling various prefabricated rooms that are manufactured and shipped to the location where they will be attached. While these homes must go through a transportation process, they also must adhere to the same zoning codes and building safety standards that traditional homes do. So what are the advantages of living in a modular home? Here are some of the most attractive benefits.

Better Quality Construction

Since the different modules making up the home have to be shipped, the components have to be strong enough to withstand the elements of transportation. As a result, the materials used are generally stronger than a traditional home. Most of the building components are the same as standard homes, but the construction process is generally more detailed and specific for a modular home.

Customized Design Options

If you want a structural glass design in your modular home, all you have to do is request it. You can combine multiple different features you like from other homes all into a single modular home. You also have the ability to design your own floor plan and even pick out details like what siding or windows should be used. The only limitations revolve around the space you have to place the modular home.

Energy Efficiency Considerations

Most of the time a modular home is built with energy efficient qualities. While custom underground homes have natural energy efficient properties, modular homes have to be constructed accordingly. Since each module of the home is designed and constructed separately, more detail and emphasis gets placed on sealants and other components to help reduce energy costs. And many times, a structural glass design can add to the energy efficient properties of a modular home.

Reduced Construction Costs

Any time you custom design a home, you have to expect the cost to be significantly higher than buying a standard home. However, with modular homes, you can enjoy full customization without having to pay outrageous construction costs. Since each smaller module is constructed individually, the process of building them is much more time efficient. Those time savings get passed on to you through lower construction costs.

BE Structural is a team of experts with a broad range of expertise. We have professionals with experience in bulk materials handling, structural inspecting, forensic engineering and much more. The advantages of a modular home are becoming more clear and evident every single day, so the popularity will undoubtedly rise in the coming years.

Structural Engineers Aim to Assist in a Zero-Waste Future

Excessive waste is a serious problem across many different industries, but it’s especially problematic in construction. It seems like no matter how much effort is put forth to reduce waste, the issue is still prevalent. Structural engineers are putting their best foot forward to create a zero-waste future, and with a continuous effort, they could be successful. From the design process to the components used and even bulk materials handling, here are ways structural engineers will have an impact on significantly reducing waste.

Detachable Building Components

Through forensic engineering investigations, results indicate a significant amount of waste can be reduced by using materials that can be detached rather than demolished. And even further in the future, the detached components could be recycled and used in other applications. Detachable components are far from being usable today, but it is something on the radar of every structural engineer.

Design For The Future

Another thing structural engineers are doing is requesting that the design teams think about the future of the building throughout the design process. Things to think about include how a building could potentially expand, be repurposed or have other functional implementation. Planning ahead in this manner could reduce the chances of having to demolish materials in order to expand or repurpose any given building.

Maintain High Performance, While Minimizing Resources

Technology is continuing to advance, whether it’s regarding facade engineering or any other component of the construction process. Structural engineers are placing an emphasis on using the latest technology to their advantage in order to use fewer resources, but still keeping performance at high levels. Many advancements in technology are designed specifically for this purpose, but they aren’t necessarily used accordingly.

Continuous Effort Will Reduce Waste

The more forensic engineering investigations that identify waste, the more structural engineers will push for a zero-waste future. We have come a long way in our efforts of reducing waste, but there is still a long way to go to eliminate it completely. When everyone involved in the construction process gets onboard with waste-reduction efforts, the better the chances are of it becoming a reality.

At BE Structural, our structural engineers and facade engineering experts constantly think about different ways to reduce waste. Through diligent and continuous efforts, we all work together and contribute to waste reduction practices.
