梁端削弱对模块化栓焊混合节点滞回性能的影响
Influence of beam end weakening on the hysteresis performance of modular bolted-welded hybrid joints
摘要
Abstract
To reveal the influence of different beam end section weakening structures on the seismic performance of modular bolted welded hybrid connection joints(MHCJs),14 MHCJs models with beam end section weakening were established by using ABAQUS and parameter analysis was conducted.The rationality of the finite element model of the joint was verified by experiments and parameter analysis.The results indicate that when the flange and web are separately weakened,it helps to reduce the stress distribution of the core module(CM)and column end steel skeleton,but increases the stress concentration phenomenon of the flange connection plate(FCP).When the flange and web of the beam end are simultaneously weakened,plastic hinges can be formed at the weakened section position of the beam end,significantly reducing the stress concentration of the CM and the damage at the FCP,improving the overall deformation and energy dissipation capacity.The research results provide theoretical support and basis for the engineering design and application of new MHCJs.关键词
