[提要]  對(duì)砌體結(jié)構(gòu)模型試驗(yàn)所常用的1/2比例磚砌體進(jìn)行了抗剪和抗壓試驗(yàn)。測(cè)得了抗剪、抗壓強(qiáng)度和軸壓下磚柱的彈性模量、泊桑系數(shù)和應(yīng)力-應(yīng)變?nèi)€的變化規(guī)律，并對(duì)它們進(jìn)行了回歸分析。所有情況下都與原型磚砌體進(jìn)行了對(duì)比試驗(yàn)。結(jié)果表明：模型磚砌體與原型磚砌體并不能保持原來(lái)的相似性。用此來(lái)分析1／2模型磚砌體結(jié)構(gòu)可得到較好的結(jié)果。

By some shear and compressive tests on l/2 model masonry spec\mens, 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 l/2 scale model masonry structures and get a good agreement with the measured.
Keywords: model masonry; shear; compression; strain-stress curve
