Progressive Collapse Analysis & Design for Federal Office Buildings

Progressive Collapse Analysis

Challenge

A number of existing building codes make varying degrees of reference to progressive collapse analysis and design. Unfortunately, in most of the existing U.S. building codes and standards that contain progressive collapse provisions, the available guidance is either vague in defining, or does not define, the key issues that must be addressed in performing a progressive collapse analysis/design. This lack of guidance from existing building codes has resulted in conflicting interpretations as to how one should approach progressive collapse analysis and/or design. 

In response to this, the United States General Services Administration (GSA) sponsored the development of progressive collapse criteria for facilities under their control. The primary goal of the criteria is to save lives and prevent injury, with a secondary goal of protecting buildings, functions/mission and assets, in the event of severe structural damage to a facility.

Solution

To facilitate the implementation of these criteria, ARA developed the “Progressive Collapse Analysis & Design Guidelines for New Federal Office Buildings and Major Modernization Projects” for the GSA.
