| 摘 要： | 对 3 6个双向受力应力状态下的灌芯砌块砌体墙片单元的强度进行了试验研究 ,由于砌体的各向异性 ,试验考虑了水平灰缝与水平面夹角及主应力比两个变化因素。研究得到两种由主应力比区分的破坏形态 ,同时根据试验数据拟合得到破坏包络面 ,从理论上推导出相应的破坏准则并与试验结果进行了比较

| Abstract: | Thirty-six panels are tested to investigate the strength of grouted concrete block masonry under biaxial stress in this paper.In the tests,due to the anisotropy of masonry,the variables are considered include the bed joint orientation,the principal stress ratio.Two distinct modes of failure were found to depend on the principal stress ratio,and the failure envelope was derived through the fit of experimental data.The failure criterion induced from theory was compared with the results of tests |
