| 摘 要： | 孔中带贯穿钢筋的开孔板连接件的基本力学性能指标是基于钢筋位于孔中心这种状态得到的.由于实际施工中钢筋位置会偏离孔中心,所以以开孔板连接件孔中钢筋位置为变化参数进行了9组共27个试件的推出试验,研究了孔中钢筋位置变化对开孔板连接件基本力学性能的影响.试验结果表明,孔中钢筋位置变化对开孔板连接件的承载力有一定的影响,但不显著；对开孔板连接件的延性和刚度影响较大.根据不同受力状态提出了开孔板连接件的抗剪刚度计算表达式.

| Abstract: | Basic mechanical behavior parameters of perfobond rib connector with transverse bar in the hole are obtained based on the state that transverse bar is located in the center of the hole.However,the position of transverse bar in the hole usually deviates from the hole center during actually construction.Nine groups,totally 27 specimens with perfobond rib connectors are designed and push-out tests are performed to investigate the influence of transverse bar position changes in the hole on mechanical behaviors ... |

| Keywords: | perfobond rib connector transverse bar position carrying capacity shear rigid ductility |
