Blast Resistant Structure Using Steel Hollow Sections

Abstract

The number of terrorist attacks has increased in the last few years, so the effect of blast loads on structures become an important matter that should be taken into consideration in the design and planning process. Terrorist attacks are exceptional cases and man-made disasters; therefore, blast loads are calculated carefully, just like earthquake and wind loads. The objective of this research is to evaluate the quality of blast load simulation for non-linear dynamic response analysis of trussed structure subjected to blast loads. This paper discusses theories for blast-resistant structural design and the enhancement of building security against the effects of explosives in both architectural and structural design processes. Steel hollow sections are used as structural members that can undergo large nonlinear deformations to absorb blast energy. Essential techniques for increasing the capacity of a structure to provide protection against blast effects are discussed in this paper from both architectural and structural perspectives.
