【摘要】 本文对14块钢筋混凝土圆板进行了强度试验,其中11块发生冲切破坏。在对圆板冲切破坏形态作了较深入的研究之后,本文提出了一种圆板冲切破坏机构,根据这个破坏机构,用经典的塑性力学理论导出了钢筋混凝土圆板在均布荷载作用下的冲切强度计算公式,该公式的计算结果与试验值符合程度良好。更多还原

【Abstract】 This paper investigates the punching strength of reinforced concrete circular slab subjected to uniform load. Fourteen specimens are tested in which eleven slabs failed due to punching shear. A punching failure pattern is given and a prediction equation is derived based on the punching failure pattern and theory of plasticity. The proposed equation has been verified by the experimental results.更多还原
