摘　　要：古北财富中心高层办公楼为一栋15层的综合办公楼,地上采用钢管混凝土框架+屈曲约束支撑结构体系,地下室为钢筋混凝土框架-剪力墙结构。由于建筑功能平面的布局以及核心区的偏心布置,导致整个结构在地震作用下呈现明显的扭转不规则特征。通过合理的布置支撑和节点处理,使其结构具有良好的屈服机制和抗震性能,并有效地解决了结构规则性超限的问题。The process of structure design for Gubei fortune comprehensive tall office building with 15-story was introduced in this paper.The CFT frame with BRB-bracing structure system on the aboveground,and reinforced concrete frame-shearwall structure in the underground is established.The architectural planning requirements and cores eccentricity enlarge the structural torsion effect when earthquake occurs.The structure has excellent order of the structure inelastic development and seismic performance with the brace reasonable established and jointed,and the problem of the structural regularity beyond the code limit is solved effectively.

关 键 词：钢管混凝土框架结构 屈曲约束支撑 节点构造 静力弹塑性分析
