Study on Blast Resistant Structure Using Steel Hollow Sections

Abstract

As the incidence of terrorist attacks has increased in recent years, the impact of blast loads on structures has become a critical issue that must be considered during the design and planning phase. Terrorist attacks are rare occurrences and man-made calamities, thus blast loads, like earthquake and wind loads, are carefully calculated. The goal of this investigation is to find out the quality of blast load simulation for non-linear dynamic response analysis of trussed structure subjected to blast loads. This study discusses blast resistant structure design theories, as well as the strengthening of building security against the effects of explosives in both the architectural and structural design processes. Steel hollow sections are employed as structural elements because they can absorb blast energy by undergoing massive nonlinear deformations. In this study, both an architectural and structural approach is taken to explain essential strategies for strengthening a structure's potential to give protection against blast effects.
