安装有防屈曲支撑建筑的地震模拟与经济性分析
|
摘要
结合防屈曲支撑拟静力实验的研究成果,用ABAQUS有限元软件模拟一栋建筑的地震反应。比较原设计结构与减少梁柱面积但安装有防屈曲支撑的减缩结构这2种方案下的地震响应,使两者的层间位移角相近并满足规范要求,进而做经济性对比。结果表明,防屈曲支撑可以有效地减小结构地震响应,并且先于梁柱破坏,保护主体结构安全;安装防屈曲支撑的结构在满足设计要求的同时,还可以节省建筑成本,缩短施工工期。
Combined with the pseudo-static experiment of buckling-restrained braces(BRBs),seismic response of a building has been simulated with finite element software Abaqus.Two kinds of design are displayed.One is the original design structure and another is the shrinkage structure with BRBs.Both have similar story drift and meet the requirements of standard.The simulation results show that the BRBs can decrease seismic response well,and protect the main structure;On the other hand,BRBs can save the construction cost,and shorten the construction period.
