BRB-钢管高强混凝土结构的抗震性能分析
|
摘要
为了研究屈曲约束支撑-钢管高强混凝土框架结构在多遇地震和罕遇地震作用下的抗震性能,结合我国抗震规范,利用通用有限元分析软件SAP2000对设置了屈曲约束支撑的三层钢管高强混凝土框架结构进行静力弹塑性分析,得到了该结构在地震作用下的能力曲线、层间位移、顶点位移和塑性铰分布情况等相关参数,并对其抗震性能进行了分析.结果表明,框架中设置的屈曲约束支撑可有效提高钢管高强混凝土结构的抗震性能,满足结构抗震性能的要求.
In order to investigate the seismic resistance of buckling-restrained brace(BRB)-high strength concrete-filled steel tube frame structure under both frequent and rare seismic action,the universal finite element analysis software SAP2000 was used to perform the static elasto-plastic analysis on a 3-storey BRB-high strength concrete-filled steel tube frame structure in combination with Chinese code for seismic design.In addition,such related parameters as the capacity curve,storey drift,vertex displacement and plastic hinge distribution of the proposed structure under seismic action were obtained.And the seismic resistance of the structure was analyzed.The results show that the BRB arranged in the frame can effectively improve the seismic resistance of high-strength concrete filled steel tube structure,and meet the requirements of seismic resistance of the structure.
