预制装配式框架连接节点性能分析及优化

Performance Analysis and Optimization of Prefabricated Frame Connection Nodes

预制构件连接方式及抗震性能可靠性是装配式钢筋混凝土结构中的关键技术和研究热点。从装配式框架结构连接形式及传力分析、装配式连接节点的抗震性能三个方面介绍了目前的研究现状。在此基础上,提出一种具有良好抗震性能的装配式钢管约束耗能框架连接节点,并阐述了该连接节点的施工流程。

Structural connection and seismic capacity were key technologies in the assembly of reinforced concrete structures. The paper introduces the research status from three aspects: the connection form and force transfer analysis of prefabricated frame structure and the seismic performance of prefabricated connection joints.Based on the analysis, a kind of assembled steel pipe restrained energy dissipation frame joint with good seismic performance was put forward to realize the seismic requirement of "strong node, weak component", " strong shear and weak bending ". Besides, the effect of the plastic hinge is reduced to the core area. At last, the construction process of the connection node is introduced.
