本文对大型室内预制组合板梁柱节点进行了试验和分析研究。四个试件在模拟地震型运动的反循环荷载下进行了试验。该节点最相关的特点是底部的梁钢筋形成并安装锚头，而不是弯曲形成直立90度挂钩或闭合环。将预制混凝土连接与整体连接进行性能比较，分析其破坏模式、滞回特性、骨架曲线、位移延性和耗能特性。试验结果为大型节理的抗震性能提供了一些信息。总的来说，关节的性能令人满意。试验未发现粘结问题和明显的夹紧效应，试件具有延性，节点强度与整体钢筋混凝土结构基本相当，但试件的延性受柱梁抗弯强度比的影响，并推荐了适用范围。
The experimental and analytical investigations carried out on large-scale interior precast beam to column joints with composite slab are presented in this paper. Four specimens were tested under reversed cyclic loading that simulated earthquake-type motions. The most relevant feature of the joint is that the beam reinforcement on the bottom was formed and installed with anchor head, rather than bent to form stand 90-degree hooks or closed loops. The performance of the precast concrete connection was compared with that of the monolithic connection, and the failure pattern, hysteretic characteristic, skeleton curve, displacement ductility and energy dissipation, were analyzed. The test results provided some information about the seismic behavior of the large-scale joint. In general, the performance of the joint was satisfactory. No bond problem and obvious pinching effect were observed in the test, and specimen behavior was ductile and joint strength was almost equal to that of monolithic reinforced concrete construction, however, the ductility of the specimens was affected by the ratio of column to beam flexural strength, and the scope of application was recommended.
