|
摘要
通过带构造柱混凝土多孔砖墙片在低周往复荷载作用下的拟静力试验,研究了带构造柱混凝土多孔砖墙片的破坏特征与机理及构造柱与墙片的协同工作机理,分析了墙片在承载力、耗能、刚度、延性和构造柱钢筋等方面随荷载变化的特征与规律,基于有限元计算、等效弹性反应原理分别分析了墙片在低周往复荷载作用下的破坏机理、墙片的抗倒塌机理,获得了较多有益结论,对推动墙体改革、建筑节能和环境保护产生积极作用,具有显著社会和经济效益,为混凝土多孔砖在抗震地区的推广应用及相关规程的编订、修改提供了依据,可供借鉴。
According to the static experiment on concrete porous brick wall with structual column under low cyclic loading,the failure mechanism and characteristics of the concrete porous brick wall with structual column are studied.And the cooperative work mechnism of structural column with the wall are investigated.At the same time,the changing rules of load capacity,energy consumption,stiffness,ductility of the wall and the reinforcing steel bar of the structural column along with the variety of load are analyzed.The failure mechanism of the wall under low cyclic loading and the collapse resistance of the wall are obtained respectively in terms of finite element analysis and principle of equivalent elastic response.Some useful conclusions are gained and bring forth to positive significance for propelling the wall reform,building energy conservation and environmental protection,which has remarkable economic and social benefits.It provides basis for the application of concrete porous bricks to aseismatic region and the editing,amending of relative rules as well as providing reference for the similar engineering application.
