Abstract A new type of plug-in assembled concrete beam–column connection based on partial steel–concrete composite structure is proposed to improve the assembly efficiency of assembled concrete structure. This paper presents experimental and numerical investigation on this plug-in assembly connection. Using the size of a section steel as a variable, low-cycle reciprocating loading tests were performed with seven plug-in assembly connection specimens and one cast-in-place joint. The response characteristics of specimens such as failure mode, hysteretic performance, skeleton curve, energy dissipation capacity, bearing capacity, stiffness degradation, and strain were compared and analysed. Owing to the combination effect of splicing zone and the geometric nonlinear deformation of different materials, the energy dissipation capacity and initial stiffness of this type of assembly connections are slightly lower than those of whole cast-in-place joints, but the bearing capacity of assembly connections is higher. The bearing capacity of plug-in connections are mainly controlled by the cross-section bearing capacity of the composite beam. With reasonable structure and high processing quality, and plug-in assembly connection will have excellent bearing performance.

插装式混凝土梁柱连接抗震性能试验研究

摘要 为提高装配式混凝土结构的装配效率，提出了一种基于局部钢-混凝土组合结构的新型插入式装配式混凝土梁柱连接。本文介绍了这种插入式组件连接的实验和数值研究。使用型钢的尺寸作为可变的低周往复载荷测试，对七个插入式组件连接试样和一个现浇接头进行了测试。对试件的失效模式、滞回性能、骨架曲线、耗能能力、承载能力、刚度退化、应变等响应特性进行了比较分析。由于拼接区和不同材料的几何非线性变形的共同作用，这种装配式连接的耗能能力和初始刚度略低于整体现浇连接，但装配式连接的承载能力更高。插入式连接的承载力主要由组合梁的截面承载力控制。结构合理，加工质量高，插入式装配连接具有优良的承载性能。
