摘　　要：珠海某公寓大楼结构总高度152m,属超B级高度的超限高层结构,采用带转换的框架-剪力墙结构。建筑平面为典型的U形平面,存在扭转不规则、凹凸不规则、竖向构件不连续等多项超限情况。为验证结构布置的可靠性和安全性,文中采用YJK和ETABS对结构进行整体计算分析及弹性时程分析,利用Perform-3D对结构进行大震弹塑性动力时程分析。结果表明结构体系安全可靠。通过有针对性的加强措施,结构整体满足预期的抗震性能目标要求。A residential apartment building in Zhuhai has a total height of 152 meters,classifying it as an ultra-tall structure of super B-level height.The building features a frame-shear wall structure with a transfer structure.The plan is a typical U-shape,presenting several irregularities including torsional irregularity,irregularities in concavity and convexity,and discontinuity of vertical components.To verify the reliability and safety of the structural design,the study employed YJK and ETABS for overall structural analysis and elastic time-history analysis,and used Per-form-3D for nonlinear dynamic time-history analysis under strong seismic conditions.The results indicate that the structural system is safe and reliable.With targeted reinforcement measures,the structure overall meets the antici-pated seismic performance objectives.
