(湖南大學(xué)土木工程學(xué)院 長沙 410082)[提要] 利用ALGOR FEA計算程序,分析了豎向壓應(yīng)力和水平力共同作用下無筋磚墻的應(yīng)力?;谖闹刑岢龅钠矫媸芰ζ鲶w的破壞準(zhǔn)則,對墻體裂縫分布進(jìn)行了描述,并提出了不同高寬比磚墻的水平開裂荷載的計算公式。最后建立了墻體抗剪承載力計算公式,其計算結(jié)果與試驗值吻合較好。所提出的方法可供砌體結(jié)構(gòu)設(shè)計和研究參考。
[關(guān)鍵詞] 磚墻 剪切 承載力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. ln 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.
