摘要
对边长比为 2～ 3的四边支承矩形板的抗冲切性能进行了试验研究 .在中心加载条件下 ,研究了四边支承矩形板的破坏形态和支座反力的分布规律 ,分析了影响四边支承板抗冲切承载力的主要因素 .在此基础上 ,提出了中心加载条件下四边支承板抗冲切承载力的计算公式 。
The shearing strength of reinforced concrete rectangular slabs supported on four sides with ratio of side length between 2 and 3 are studied in this paper. With a central concentrated load, all the failure models of these specimens are punching failure, and the supported forces are distributed over a local area. The main factors influencing the shearing strength of the slabs are analyzed. Based on those results, a method for calculated the shearing strength of such slabs are proposed.
