摘要
PBL剪力连接件是一种新型的剪力连接件,具有较高的抗剪承载力。阐述了连接件的破坏机理,分析了混凝土强度、开孔钢板孔洞直径和个数、钢板端部截面积以及贯穿钢筋的直径和强度对PBL剪力连接件承载力的影响。并根据这些试验结果回归出了有和没有端部混凝土承载作用时PBL剪力连接件极限承载力的计算表达式。
As a new type of shear connector, PBL shear connector has high shear resistance. The failure mechanism of the PBL shear connector is described, and the influence of the factors which include concrete strength, diameter and number of connector holes, cross-sectional area of the end of the connector, diameter and strength of transverse rebar on the beating capacity of PBL shear connector is analyzed. In addition, according to the test results, the equations for predicting the ultimate bearing capacity of PBL shear connector with and without considering end bearing effect are put forward.
