框架结构抗倒墙的工作机理
|
摘要
结合框架结构在地震作用下的倒塌破坏分析,简单介绍了框架结构抗倒塌能力的主要影响因素及目前常用的分析方法,指出增加框架结构的意外安全储备是提高其抗倒塌能力的有效途径。受到实际震害的启发,提出将具有滞后受力和备用传力路径等特性的部分填充墙作为抗倒墙使用,并介绍了抗倒墙的基本要求。通过仿真计算比较了纯框架结构、布置填充墙的框架结构以及布置抗倒墙的框架结构的基本倒塌破坏模式,结果表明,抗倒墙能够有效地提高框架结构的抗倒塌能力,该结构形式具有成本低,施工方便等优势,值得在广大经济不发达地区推广应用。
Based on the collapse analysis of frame structures subjected seismic load,main influence factors and current common measures for the collapse resistant capacity are introduced briefly.It is predicted that increasing the accidental safety margins is an effective approach to improve the collapse resistant capacity of frame structures.According to the actual seismic damage,some infill walls are suggested to use as the collapse resistant wall(CRW) in terms of lag mechanical behavior and reserve route.The basic requirements of the collapse resistant wall are proposed as well.The basic collapse modes of a bare frame,a frame with infill walls and a frame with both infill walls and collapse resistant walls are compared due to simulation analysis.The result indicates that the collapse resistant wall can improve collapse resistant capacity of frame structures effectively.Besides,this kind of structure form has advantages in both costs and construction,so it is worth popularizing and applying in wide economically underdeveloped areas.
