摘　　要：昆明西山万达广场写字楼为高烈度设防地区的超高层建筑,建筑总高度为316m,结构的地震响应非常显著。采用带加强层的钢管混凝土框架-型钢混凝土核心筒混合结构体系。设计中通过控制结构自重、合理分配外框架刚度、设置有限刚度的加强层和采用带约束多型钢剪力墙等技术,充分利用各结构构件的受力特点,从而提高了结构体系的抗侧刚度,控制了结构主材用量。小震和大震弹塑性分析结果表明,结构的各项指标满足规范要求,能达到预期的抗震性能目标。本项目的设计满足了高烈度区超高层结构安全、经济和美观实用的要求。The offiee huilding of Xishan Wanda Plaza in Kunming is a super high-rise building in the area of high seismic precautionary intensity. It has a total building height of 316m and structural seismic response is very large. It adopts mixed structural system of concrete filled steel tubular frame-steel reinforced concrete corewall with strengthened stories. Different technologies were used in design, including controlling structure self-weight, reasonable frame stiffness distribution, setting strengthened stories with finite stiffness and adopting constrained multi steel reinforced concrete shear wall, and the mechanical characteristics of the structural members were made full use to improve the lateral stiffness of the structural system and control material use of the strueture. Elastic-plastic analysis resuhs show that all indices of the structure meet the code requirements. The design of this project meets safe, economie, beautiful and practical design requirements for super high-rise building in high seismic intensity region.
