工程结构抗爆技术的研究现状

Anti-explosion technology in engineering structure

由于恐怖袭击活动越来越频繁,爆炸对生命和财产造成的危害极其严重,所以国内外学者进行了大量关于爆炸的试验和分析.在总结国内外大量关于抗爆研究文献的基础上,阐述了建筑结构常用的抗爆方法.主要从材料和结构形式两方面进行了说明.文中介绍了几种防爆结构的分析方法,包括能量分析方法、有限元分析方法以及反应谱分析方法,分析了抗爆研究的难点和方向.这对了解和掌握防爆的基本方法和研究现状,进行建筑结构防爆的深入研究具有指导意义.

The increasing number of terrorist attacks have posed a severe threat on lives and properties . Experiments and analyses on explosion have been carried out by many researchers. In this paper, the usual blast-resistant methods of building structure have been proposed on the basis of plenty of documents, including material and structure. Several kinds of analytic methods on explosion preventing structures are systemically introduced, including energy analysis, finite element analysis,as well as response spectrum analysis. The direction and difficulties of anti-explosion researches are proposed. It is very useful for the reader to understand the basic ways and research status about the structure. It is also very helpful for the reader to research the architecture and structure engineering to resist blast load.
