摘要
针对历次地震中多数框架结构为不利抗震的剪切型破坏这一现象,简要介绍了影响框架结构破坏机制的因素,以顶点承受集中荷载的框架结构为对象,从本质上研究了结构整体抗剪刚度和抗弯刚度对其破坏机制的影响,找到了影响结构整体抗剪刚度和抗弯刚度的因素,并提出了改变框架结构破坏机制的可行性方法。
In all previous earthquakes, many frame structures are shear-type failure mechanism, which is bad for anti-seismic. Targeted to this phenomenon, this paper briefly introduces the factors of frame structures＇ failure mechanism, taking a flame structure under concentrated load at top for example, essentially studies the effects of whole shear stiffness and bending stiffness of flame structure on failure mechanism, finds factors which affects the whole shear stiffiness and bending stiffness, and puts forward some improvement measures for changing the failure mechanism.
