摘　　要：海口市某超高层住宅结构高度149.9m,平面呈Y形,为超B级高度的超限高层建筑,采用剪力墙结构体系,存在扭转不规则、凸凹不规则等不规则项。针对该项目特点,结合建筑方案需求,经过多方案对比,确定采用钢筋混凝土剪力墙结构,并对剪力墙布置进行了分析探讨,采取了提高抗侧刚度、减小扭转效应、减轻结构自重等措施,使得到的设计为最优设计;通过合理设置型钢抵抗小偏心受拉墙体的拉应力;结构一方向剪力墙偏少,采取相应的构造加强措施,减小地震效应的不利影响。分析结果表明,结构各项指标均能满足规范要求,实现了拟定的抗震性能目标。A super high-rise residential building in Haikou,with a structural height of 149.9 meters,has a Y-shaped floor plan and is classified as an ultra-limit high-rise building exceeding B-leve height.The building adopts a shear wall structural system,with irregularities such as torsional irregularity and concave-convex irregularity.Considering the characteristics of the project and the requirements of the architectural scheme,after comparing multiple schemes,a reinforced concrete shear wall structure was chosen.The layout of the shear walls was analyzed,and measures were taken to enhance lateral stiffness,reduce torsional effects and lighten the structural weight,resulting in an optimal design.Steel members were rationally used to resist the tensile stress on walls subjected to small eccentric tension.In one direction,the building has relatively few shear walls,so corresponding structural reinforcement measures were implemented to mitigate the adverse effects of seismic activity.The analysis results show that all structural indicators meet the code requirements,achieving the intended seismic performance objectives.
