摘要:

对开孔钢板连接件（PBL）加劲型钢管混凝土构件界面粘结性能进行研究，以PBL加劲肋的开孔间距、开孔孔径、混凝土粗骨料粒径为参数，进行了该类试件抗剪性能的推出试验，并与普通钢管混凝土试件进行了界面粘结强度、抗剪刚度等参数的对比分析，提出了钢管混凝土内PBL加劲肋承载力受混凝土粗骨料含量影响的修正计算方法。结果表明：通过设置PBL加劲肋可以明显提高钢管混凝土的界面抗剪承载力和刚度，其粘结强度受加劲肋开孔参数的影响；引入的PBL抗剪承载力公式修正系数与开孔板内混凝土榫的粗骨料面积比呈线性关系。

Abstract:

The interface bond properties of PBL stiffened concrete-filled steel tube component were studied. The shear behavior push-out test of the specimens was carried out based on PBL stiffener hole spacing, hole diameter, concrete coarse aggregate size. The test results were compared with ordinary concrete-filled steel tube specimens on interface bonding strength and shear stiffness. The modified calculation method of bearing capacity of PBL stiffener in concrete-filled steel tube influenced by concrete coarse aggregate content was presented. The results show that the shear bearing capacity and stiffness of concrete-filled steel tube can be obviously increased by setting PBL stiffener. The bond strength and shear modulus are affected by the stiffener perforated parameters. The correction coefficient to modify the original PBL shear bearing capacity formula is linear with area ratio of the coarse aggregate of concrete tenon inside the perforated plate.
