Dr. Erdem specializes in evaluation, failure investigation, and repair of structures. He has significant experience in condition assessment of buildings and industrial structures, repair design, effects of adjacent construction, diagnosis of construction and design defects, and evaluation of building components compliance with applicable building codes and standards. His investigations have included evaluation of reinforced concrete, light-gage steel, masonry, wood and composite construction, as well as evaluation of means of egress, and building envelope. He has also investigated stairs, ramps and other walking surfaces for serviceability and compliance with codes and other industry standards. Dr. Erdem has developed repair/strengthening techniques for masonry walls, concrete structures and steel members. As part of his investigations, Dr. Erdem often utilizes state-of-the-art computer modeling to determine the behavior of complex structural systems under extreme loading.

Dr. Erdem’s structural collapse investigations have included buildings, cranes, roofs, bridges, masonry walls, cold formed steel walls, scaffolding, swimming pools, ceilings and retaining walls. He has investigated buildings and industrial facilities damaged by Hurricane Sandy, and evaluated the cause(s), nature, extent and appropriate repairs. Dr. Erdem inspected buildings that were damaged or collapsed by the Bingol, Turkey in May 2003, and reviewed engineering issues associated with numerous buildings that collapsed during the 1999 Marmara Earthquake.

Prior to joining Exponent, Dr. Erdem was a research assistant at Cornell University, where he conducted nondestructive testing (impact echo) of graphite rods and developed a new finite element model of the human thoracolumbar spine. He was the instructor for a graduate-level course on concrete structures for two semesters, in addition to being a teaching assistant for several other classes.
