DYNAMIC EFFECTS IN STRUCTURAL RESPONSE TO IMPACT AND BLAST LOADS

摘要：

　　A series of dynamic effects is involved in the course of structural response to impulsive loads such as impact and blast,and these vary from the high strain rate effect at the material level,various dynamic failure modes at the structural component level,to the dynamic amplification associated with the transition to a typical double-span mechanisms in the process of the progressive collapse due to a sudden removal of column member.This paper discusses the characteristics of these different dynamic effects and introduces some associated research studies.The governing mechanisms in the different regimes of the dynamic effects are highlighted and appropriate analytical and numerical modeling approaches are discussed.
