不同类型钢-混凝土组合剪力墙超高层结构抗震性能对比

摘要

The seismic performance of frame-core tube structures with steel plate reinforced concrete (RC) shear wall, RC shear wall with concealed steel truss, and traditional steel reinforced concrete shear wall are investigated respectively by conducting dynamic and static elasto-plastic analysis with the aid of structural analysis software Per-form-3D. Influences of three types of composite shear walls on the dynamic characteristics, displacement responses, and seismic damage of the whole structure are investigated. The study indicates that the seismic performance of the structure with steel plate RC shear walls is the best and that of the structure with RC shear wall with concealed steel truss is better than that of the structure with traditional steel reinforced concrete shear wall.%采用结构分析软件Perform-3D对分别带有内置钢板混凝土组合剪力墙、内藏钢桁架混凝土组合剪力墙以及传统的型钢混凝土剪力墙的框架-核心筒结构进行静力和动力弹塑性分析,研究了三种剪力墙对整体结构的动力特性、位移反应和地震损伤的影响.研究表明,带有三种组合剪力墙的结构整体抗震性能优劣顺序依次为内置钢板混凝土组合剪力墙结构、内藏钢桁架混凝土组合剪力墙结构、型钢混凝土组合剪力墙结构.
