摘要(Abstract):

对砌体结构模型试验所常用的1/2比例砖砌体进行了抗剪和抗压试验.测得了抗剪、抗压强度和轴压下砖柱的弹性模量、泊桑系数和应力-应变全曲线的变化规律,并对它们进行了回归分析.所有情况下都与原型砖砌体进行了对比试验.结果表明:模型砖砌体与原型砖砌体并不能保持原来的相似性.用此来分析1/2模型砖砌体结构可得到较好的结果.
By some shear and compressive tests on 1/2 model masonry specimens, the shear strength, compressive strength, elastic modulus and whole strain-stress curve are measured and regressed. They are also compared with the prototype masonry. It is shown that model masonry doesn't completely have a resemble to the prototype one. Those results are used to analyse certain 1/2 scale model masonry structures and get a good agreement with the measured.
