Any engineered structure is expected to function properly under the loads it’s designed for. The expected structural functionality varies widely, from an imperceptible floor vibration response to maintaining structural integrity under extreme loads. But sometimes, structures fail to meet such criteria. We have evaluated various types of structural failures with different levels of complexities. Through forensic engineering, we explore the roots and causes of structural failures. This needs detailed investigations, cutting-edge knowledge in structures and problem-solving skills to spot the key points, connect the dots together and figure out the problem. Dr. Pirmoz has investigated the collapse of various structures and done a reconnaissance of the catastrophic 2003 Bam Earthquake. Part of the study was on the unique behavior of a castellated steel beam which had been damaged in the earthquake, which was later published in the International Journal of Steel Structures (read here).
