摘要
本文研究的是一种软钢阻尼器梁柱节点,并根据有无软钢阻尼器模拟的框架结构,在不同的地震波进行时程分析,为该节点的设计和建筑施工提供参考。利用ABAQUS有限元软件的数值模拟,对有无软钢阻尼器两种节点建模分析,从两种节点的滞回曲线、骨架曲线、耗能能力、刚度退化等抗震性能进行定量分析。结果表明有阻尼器的节点各力学性能均强于无阻尼器的节点,并且在有控情况下可以显著消耗建筑结构的地震能量,减小地震反应。因此本节点在有控情况下有利于装配结构在高烈度地区的推广使用,可以有效提高装配式结构的抗震性能,为装配式建筑施工在实际应用中提供参考。
In this paper,time history analyses of the two assembled beam-column nodes with and without soft steel dampers were obtained by finite element software Abaqus under loading of different earthquake waves.The simiulations results provide a reference for the design and building construction of this node.The quantitative analyses of the two nodes for hysteretic curves,skeleton curves,energy dissipation capacities,stiffness degradation and other seismic behaviors were carried out.The results show that the nodes with dampers have stronger seismic properties than those without dampers,and can significantly consume the seismic energy of the building structure and reduce the seismic response under controlled conditions.Therefore,this node is conducive to the promotion of the use of assembled structures in high seismic fortification intensity areas under controlled circumstances,can effectively improve seismic performance of assembled structures,provide reference for assembly building construction in practical application.
