Abstract :
There are important differences between seismic-resistant design and blast-resistant design, despite the dynamic nature of both. Design of structures to resist seismic forces depends in ductility and the capacity of elements and their connections to undergo large deflections and rotations without failing. The use of several shear walls distributed throughout the building will improve the overall seismic as well as the blast behavior of the building. The perimeter walls may be connected to adjacent columns or not. This study was focused on the potential loss of columns against blast loading when connected to the shear wall. The computer program AUTODYN and SAP2000 were used to model and analyze. This paper includes evaluation for the loss of adjacent columns and the potential for failure of structure. The weaknesses present in the structural blast design are assessed, and recommendations for improved detailing are offered.
