为了研究柱截面形式为异形柱的板柱连接冲切受力性能,进行了柱截面形状分别为3种典型异形柱(十字形、T形和L形)和对比方柱所构成的板柱连接的冲切特性试验.根据所进行的柱截面为十字形异形柱-板柱连接冲切特性的试验成果,提出了十字形柱-板柱连接的屈服线形式,并应用屈服线理论,导出了十字形异形柱-板柱连接的抗弯承载力表达式.该式形式简单、应用方便,其理论计算值与试验值比较,符合较好.结果可供类似柱形的板柱连接强度计算时参考. In order to study the punching shear force of column-column connection with special-shaped columns, the column cross-sections of three typical special-shaped columns (cross, T and L) According to the test results of cross-section cross-section column-plate column connection punching characteristics, the yield line form of the cross-column-plate column connection is proposed and the yield line theory is applied to derive the The results show that the formula is simple and easy to use, and its theoretical value is in good agreement with the experimental value.Results It can be used to calculate the connection strength of plate column with similar column shape reference.
