钢箍板连接装配式混凝土柱-钢梁节点抗震性能研究
Research on seismic performance of prefabricated concrete column-steel beam joints with steel hoop plate connections
摘要
Abstract
To address the poor seismic performance and low construction efficiency of prefabricated building structural joints,this study proposes a novel prefabricated concrete column-steel beam joint with steel hoop plate connections.A finite element model of the joint was developed using ABAQUS and validated against full-scale cyclic loading tests.Parametric analysis demonstrated that increasing the steel hoop plate thickness improves joint stiffness and load-bearing capacity,while a higher internal diaphragm thickness(within a practical range)enhances initial stiffness;however,axial compression ratio has minimal influence on these properties.Based on these findings,a preliminary design-stage formula for estimating the joint's shear capacity was derived.关键词
