移动硅谷创新中心二期项目7#楼采用现浇钢筋混凝土框架-核心筒结构体系,为满足首层及2层大空间的要求,在首层和2层拔去了2根柱子,存在局部转换。主要针对该项目结构设计中转换桁架的性能化设计、首层室内地面与外围地下室顶板存在较大高差时如何实现上部结构在地下室顶板嵌固、地基基础的变刚度调平设计等几个关键问题进行讨论。通过对结构进行计算和对比分析得出,结构能够满足安全和建筑功能的要求,实现了“三水准”抗震设防性能目标。
The 7th floor of Mobile Silicon Valley Innovation Center Phase II project adopts the cast-in-place reinforced concrete frame-core tube structural system. In order to meet the requirements of the first floor and the second floor, two pillars are removed on the first floor and the second floor, . Mainly for the structural design of the conversion truss performance of the design, the first floor of the indoor basement and the outer basement roof when there is a large difference in how to achieve the superstructure in the basement ceiling embedded in the foundation of the variable stiffness leveling design and several other key Discuss the problem. Through the calculation and comparison analysis of the structure, the structure can meet the requirements of safety and building function, and achieve the target of “three levels” seismic fortification performance.
