摘　　要：通过对 13块四边简支叠合双向板在集中荷载作用下的受冲切试验研究 ,分析了试验板的受力工作机理、裂缝、钢筋应变、支座反力特性和板的破坏形态。试验结果表明 :在集中荷载作用下 ,四边简支钢筋混凝土叠合双向板的破坏形态均为无预兆的脆性冲切破坏。据此 。According to the shear test results of 13 specimens simply supported reinforced concrete composite two way slabs under concentrated load,the failure patterns and behaviors of the specimens are described and analyzed.The results show that all the failure modes of these specimens are brittle punching failure without any signs.The proposed calculating method of punching bearing capacity of such elements is put forward.
