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.
