摘要
利用ALGORFEA计算程序 ,分析了竖向压应力和水平力共同作用下无筋砖墙的应力。基于文中提出的平面受力砌体的破坏准则 ,对墙体裂缝分布进行了描述 ,并提出了不同高宽比砖墙的水平开裂荷载的计算公式。最后建立了墙体抗剪承载力计算公式 ,其计算结果与试验值吻合较好。
The stress of unreinforced brick wall under vertical compression and horizontal force has been analysed by ALGOR FEA computer software.The formulas for calculation of horizontal cracking load of brick wall of different ratio of height to width have been proposed on the basis of failure criterions of plane stress masonry.The crack distribution of wall has been described in detail.In the end,the calculating formula of shear load bearing capacity of wall has been established.The calculating results agree well with the experimental data.This method can provide reference for masonry structural design and research.
