【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。
[Abstract]:The office building of West Mountain Wanda Square in Kunming is a super high-rise building in high intensity fortification area. The total height of the building is 316 m.The seismic response of the structure is very remarkable. Concrete-filled steel tube (CFST) frame-steel reinforced concrete (SRC) core tube hybrid structure system with reinforced layer is adopted. In the design, by controlling the weight of the structure, distributing the stiffness of the outer frame reasonably, setting the strengthened story with finite stiffness and adopting the technique of multi-section steel shear wall with constraints, the mechanical characteristics of each structural member are fully utilized. Thus, the lateral stiffness of the structure system is improved, and the amount of the main material is controlled. The results of elastic-plastic analysis of small and large earthquakes show that each index of the structure can meet the requirements of the code and achieve the expected seismic performance goal. The design of this project meets the requirements of high-rise structure safety, economy and beauty.
