摘要

摘要: 为研究竹混凝土组合结构开孔钢板连接件的力学性能，进行了竹混凝土开孔钢板剪力连接件的推出试验研究。结果表明：竹混凝土钢板连接件的典型破坏形态主要表现为开孔钢板屈服、混凝土部分剪切压溃、开孔钢板在竹材部分滑移几种模式，开孔钢板屈服大多发生在竹混凝土钢板连接件，竹混凝土钢板连接件的荷载-滑移曲线在峰值荷载之后，都能够维持较高的残余荷载值，荷载下降缓慢，无论是否配置贯穿钢筋，破坏模式都属于延性破坏，其界面滑移沿着界面高度分布均匀；竹混凝土钢板连接件的承载力由开孔钢板与竹材连接界面的承载力、开孔钢板与混凝土连接界面的承载力、界面处最薄弱截面开孔钢板的抗剪承载力三个方面决定，基于此建议了其承载力分析方法。

Abstract: To investigate the mechanical properties of the perforated plate shear connections for bamboo-concrete composite structures, the push-out tests on the perforated plate connectors were conducted. The results showed that the typical failure modes of perforated plate shear connections of bamboo-concrete composite structures were the yield of the perforated plate, partial shearing crushing of the concrete, and the slipping of the perforated plate in the bamboo section. The yield of the perforated plate occurred mostly at the perforated plate shear connections of bamboo-concrete. The load-slip curves of perforated plate shear connections of bamboo-concrete structures maintained a high residual load value after reaching the peak load, and the load dropped slowly. The failure modes were ductile no matter whether setting perforated steel bar of not, and its interface slipped evenly along the height of the interface. The bearing capacity of perforated plate shear connections of bamboo-concrete structures were determined by three factors, which were the bearing capacity of the interface between the perforated plate and bamboo, the bearing capacity of the interface between the perforated plate and concrete, and the shear resistance of the weakest section of the perforated plate at the interface. Based on the test results, the analysis method of the bearing capacity was proposed for the perforated plate shear connections of bamboo-concrete structures.
