摘　　要：珠海长隆航海酒店为部分框支剪力墙结构,结构存在扭转不规则及偏心布置,凹凸不规则,楼板不连续,尺寸突变,构件间断和局部穿层柱等6个不规则项,属于超限高层建筑。介绍了工程的特点和结构设计情况;进行了小震弹性时程分析和大震弹塑性分析;针对分析的薄弱部位相应采取了严控轴压比,增加底部加强区域剪力墙配筋率,在特定位置混凝土柱及剪力墙中增设型钢,提高特定位置抗震等级,加强薄弱部位楼板板厚及配筋等抗震加强措施。通过基于性能的抗震设计,可以达到预期的C级性能目标和规范要求。Zhuhai Chimelong Marine Hotel is a partial frame-supported shear wall structure with 6 irregular items,including irregular torsion and eccentric arrangement,irregular concave and convex arrangement,floor discontinuity,size mutation,component discontinuity and local skip-layer columns.The characteristics and structural design of the project were introduced.Elastic time-history analysis for the building under frequent earthquakes was conducted as well as elasto-plastic analysis.Seismic strengthening measures were taken such as strict control of axial compression ratio adopted for the weak parts of the analysis,increasing reinforcement ratio of shear wall in bottom reinforced area,adding profiled steel to concrete columns and shear walls at specific locations,improving the seismic grade at a specific location,and strengthening floor slab thickness and reinforcement in weak parts.Through the performance-based seismic design,the expected C-class performance target and specification requirements could be achieved.
