PROGRESSIVE COLLAPSE |

The ISC Security Design Criteria includes requirements to make all new designs less vulnerable to progressive collapse. Structures undergoing major rehabilitation and/or seismic rehabilitation are required to be analyzed using these criteria, to assess the feasibility of including upgrades in major projects. Progressive collapse analysis is not an analysis of the effect of a blast—it is event-independent. The purpose of the analysis is to determine a structure’s ability to survive the loss of individual vertical load-carrying elements. The analysis is best accomplished by a structural engineer that is familiar with the behavior of structural systems, components and connections. The joint venture team includes structural engineers with expertise in a broad range of building construction types and the performance of analyses for progressive collapse. The joint venture offers WAI principals that have participated in the development of the progressive collapse guidelines used by federal agencies. |
