摘要
通过90个烧结多孔砖砌体三砖模型在不同轴压比下的抗剪试验,初步探明了多孔砖砌体在剪压复合受力下的破坏形态及破坏机理。经对试验数据的回归分析得到抗剪强度计算公式,并与实心砖砌体进行了比较分析,揭示出砖孔洞对砌体复合抗剪能力的影响规律,从而对剪压复合受力理论及抗剪强度计算方法进行了补充与发展,给出了相应的算式。
Through the shear strength test of the model of three fired perforated bricks under different axial compression ratio, the failure form and theory under shear-compression combined loading are studied. After the regressive analysis of the test data, the combined shear strength calculating formula is obtained. The comparison of formula between perforated and common brick masonry shows the influence of brick＇ s holes upon the combined shear strength. Complement and development to shear theory and calculating method of strength are presented.
