Description
Summary:This paper describes the recently developed FACEDAP (Facility and Component Explosive Damage Assessment Program) computer program, which provides a quick estimate of blast damage to conventional buildings from external detonations. It uses a blast damage assessment procedure which is based on dynamic structural analysis theory and is validated against available data from explosive tests on structural components. The code assesses blast damage to each structural component in a conventional building and then calculates the composite building damage based on the summed component damage. It is intended to predict the actual amount of building damage, without the conservatism that is often built into such analyses, within the accuracy permitted by simplifying assumptions that have been incorporated to maintain efficiency. This paper describes the building damage assessment procedure, shows comparisons between predicted component damage and data from explosive tests, and discusses limitations of the code caused by simplifying assumptions that have been incorporated.
