摘　　要：采用不同强度的砂浆砌筑矩形孔烧结页岩砖砌体抗剪试件,按砂浆强度等级分为3组共计27个,并进行抗剪强度试验,研究其抗剪承载能力.试验结果表明:矩形孔烧结页岩砖砌体受剪破坏具有明显的脆性破坏特征.通过对试验数据的回归分析,提出了矩形孔烧结页岩砖砌体抗剪强度计算公式.公式计算结果验证了对于同一强度等级的砂浆,矩形孔烧结页岩砖砌体抗剪强度高于现行砌体设计规范的抗剪强度取值,表明规范抗剪强度取值适用于矩形孔烧结页岩砖砌体且有一定的安全储备.Twenty-seven sintered shale brick masonry specimens are divided into three groups according to themortar strength for shear strength test. The result of the test shows that the destruction of rectangular hole sinteredshale brick is brittle failure. Based on the regression analysis of experimental data, the shear strength calculationformula of rectangular hole sintered shale brick masonry was proposed, which shows that average of rectangular holesintered shale brick masonry shear strength is higher than the value of the shear strength in current masonrystructures code with the same strength grade mortar. It also indicates that the current masonry structures code isapplicable to the rectangular hole sintered shale brick masonry with enough safety coefficient.
