ABSTRACT
Recently, the special design requirement of buildings against blast load becomes more and more important for the safety of the occupants. The UK SCI publication 244 [1] provides a guidance on the design of commercial and public buildings where there is a requirement to provide protection against the effects of explosions caused by the detonation of explosives. In United States, FEMA 426 [2] provides the design measurements to reduce physical damage to the structural and non-structural components of building and related infrastructures during conventional bomb attacks, as well as attacks using chemical, biological and CBR agents. However, due to the huge cost, it is almost impossible to investigate the response of the multistory buildings against blast loads with full-scale experimental tests. Therefore, advanced numerical tools such as the finite element method become the main approach for the related research. The analysis and design of structures subjected to blast loads require a detailed understanding of blast phenomena and the dynamic response of various structural elements. However, most of the current numerical modeling research is involved with massive computational time and the model is difficult to build due to its complexity. Therefore, for designers, it is imperative to establish a simple modeling method to study the detailed behavior of the building after the blast denotation.
