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 Gubei Fortune Center high-rise office building is a 15-storey office building with a concrete filled steel tube frame and buckling restrained structural system. The basement is a reinforced concrete frame-shear wall structure. Due to the layout of the building’s functional plane and the eccentric arrangement of the core zone, the whole structure shows obvious torsional irregularities under the action of the earthquake. By reasonably arranging support and joint processing, the structure has good yielding mechanism and seismic performance, and effectively solves the problem of structural regularity overrun.
