摘要
全框支剪力墙结构属于一种全新的结构体系,常用与地铁车辆段综合开发项目,并与大底盘和多塔结构相结合。本工程存在扭转不规则、刚度突变、尺寸突变、构件间断等不规则项,结构计算中,采用YJK和MIDAS软件分别进行静力弹性分析,采用SAUSAGE软件进行动力弹塑性分析,并提出了对应的加强措施。表明此方案具有较高的延性和抗震承载力,结构抗震性能达到且优于设定的性能目标,为同类工程设计提供参考。
The frame supported shearwall structure is a new structural system,which is often combined with the comprehensive development project of Metro Depot,big chassis and tower structure.The project has irregular items such as torsional irregularity,sudden change of stiffness,sudden change of size and member discontinuity.In the structural calculation,YJK and Midas programs are used for static elastic analysis respectively,and SAUSAGE program is used for dynamic elastic-plastic analysis,and the corresponding out of limit strengthening measures are put forward.It shows that this scheme has high seismic bearing capacity and ductility,and the seismic performance of the structure reaches and is better than the set performance target,which provides a reference for the design of similar projects.
