本文介绍了高强混凝土与普通混凝土抗剪强度的试验研究.指出:纵向剪切试件的剪切面高度是影响剪切面剪应力分布的主要因素;抗剪强度随剪切面高度的增加而有所降低;普通混凝土抗剪强度与抗压强度之比较高强混凝土的高.同时,给出了纵向剪切试验和横向剪切试验所得抗剪强度与抗压强度的关系式,和提出了从横向剪切试验所得抗剪强度换算成纵向剪切试验的抗剪强度的建议.
This paper introduces the experimental study on the shear strength of high-strength concrete and ordinary concrete. It is pointed out that the shear surface height of longitudinal shear specimen is the main factor that influences the shear stress distribution of the shear surface; the shear strength increases with the height of the shear surface. The shear strength and compressive strength of ordinary concrete are compared with that of high-strength concrete. At the same time, the relation between shear strength and compressive strength obtained from longitudinal shear test and transverse shear test is given, and The shear strength obtained from the transverse shear test is converted into the shear strength of the longitudinal shear test.
