Blast Resistant Structure Using Steel Hollow Sections

Abstract

The number of terrorist attacks increased in the last few years, so the effect of blast loads on structures become an important matter which should be taken into consideration in the design and planning process. Terrorist attacks are exceptional cases and man-made disasters, so blast loads are calculated carefully just like earthquake and wind loads. The objective of this research is to determine the quality of blast load simulation for non-linear dynamic response analysis of trussed structure subjected to blast loads. Blast resistant structure design theories, the enhancement of building security against the effects of explosives in both architectural and structural design process are discussed in this paper. Steel hollow sections are used as structural members those 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 both with an architectural and structural approach.
