抗剪性能是砌体结构的重要性能之一。通过标准砌体构件抗剪试验,研究了再生砂浆多孔砖砌体的抗剪强度、破坏特征,并与《砌体结构设计规范》(GB50003-2011)中的普通多孔砖砌体计算公式相比较,给出了再生砂浆多孔砖砌体抗剪强度设计值的建议取值。试验及结果分析表明:再生砂浆体具有很好的强度和变形能力,可作为砌体结构中的砌筑砂浆。
Shear resistance is one of the most important properties of masonry structures. Through the shear tests of standard masonry members, the shear strength and failure characteristics of recycled mortar porous brick masonry are studied and compared with the calculation formula of ordinary porous brick masonry in “Code for Design of Masonry Structure” (GB50003-2011) , Gives the recommended value of the shear strength of recycled mortar porous brick masonry design value. The test and result analysis show that the recycled mortar body has good strength and deformation capacity and can be used as the masonry mortar in the masonry structure.
