摘要
分析了国内外不同学者基于推出试验得出的PBL剪力连接件抗剪承载力计算公式,运用这些公式对诸学者各自的有钢翼缘PBL剪力连接件推出试验试件进行了承载力计算。通过对比分析公式计算结果与试验结果,讨论各种不同抗剪承载力计算公式的适用性和准确性。结果表明,Verissimo和Medberry提出的计算式分别适用于孔洞中无贯穿钢筋和有贯穿钢筋的PBL剪力连接件。
T he calcutation formulas for the bearing capacity of PBL-type shear connectors were put forward based on the previous push-out tests. T he bearing shear capacity of all PBL-type shear connector push-out test specimens with the steel flange were calculated and compared. T he adaptability and accuracy of the different formulas for the bearing shear capacity of PBL-type shear connector was discussed. It indicated that the formula proposed by Verissimo and M edberry respectively can be used to predict the capacity of PBL-type shear connector w ith perforating bar or w ithout perforating bar.
