分析汶川“5·12”震害 探求房屋“大震不倒”途径
|
摘要
本文围绕"大震不倒"主题,对汶川"5.12"特大地震震害进行了分析探究。文中涉及"大震不倒"设防目标、研究方法、房屋倒塌的震害特点等问题;对倒塌房屋分为薄弱层垮塌、沿开间垮塌、不规则体型垮塌3种类型进行了讨论,分析了垮塌的原因并提出了看法;同时还对"强梁弱柱"现象做了分析。最后,扼要对混凝土框架结构和砖混结构提出"大震不倒"的建议性意见。
Through investigating the building destruction in "5.12" Wenchuan earthquake, this paper focus on the anti-collapse design for strong earthquake. The issues discussed in the paper includes seismic fortification criterion, research methods, and the characteristic of earthquake which made causes collapse. The matters of weak story collapse, weak-bay collapse, irregular building collapse and "strong beam and weak column", are also involved in. Finally, some suggestions of anti-collapse design for strong earthquake are proposed.
