【摘要】 为获得多孔砖砌体结构平面应力状态下的强度破坏曲线,基于单轴力学性能试验,借鉴现行标准中试验方法,分别进行多孔砖砌体通缝抗压强度试验、顺缝抗压强度试验、通缝抗拉强度试验和顺缝抗拉强度试验。试验结果符合砌体结构抗压强度高而抗拉强度低的基本力学特性,试验数据可用于确定平面应力强度破坏曲线坐标轴控制点,抗拉强度试验方法可在各类砌体结构抗拉强度测试试验中加以推广应用。更多还原

【Abstract】 In order to obtain the plane stress strength curve of masonry structure,based on the experimental research of mechanical properties and the test method in current specification,several kinds of tests were carried out,including horizontal compressive strength tests,vertical compressive strength tests,straight-line joint tensile strength tests and vertical tensile strength tests. The results of these tests conforms to the basic mechanical properties of masonry structure with high compressive strength and low tensile strength. The test data could be used to determine the key points on the axis of the plane stress curve. Besides,the method of tensile strength tests in the paper could be applied in all kinds of tensile strength tests for masonry structures.更多还原
