中国光谷科技会展中心结构设计

SEISMIC DESIGN OF OPTICS VALLEY SCIENCE AND TECHNOLOGY EXHIBITION CENTER

中国光谷科技会展中心为大体量超限钢结构建筑,有6项超限项,采用钢管混凝土框架-中心防屈曲约束支撑结构体系。介绍了防屈曲约束支撑的设计过程以及结构性能化设计分析过程,分析结果表明:该结构体系在地震作用下达到了既定的性能目标,有较好的性能表现。此外,还对跨层通高柱的稳定性、减小钢结构装饰幕墙对主体结构影响等关键问题进行了讨论。

Optics Valley Science and Technology Exhibition Center is a large volume of out-of-code steel structure building, adopts the concrete-filled steel tubular frame-central buckling restrained brace structure system, has six indicators out of existing codes. The design process and method were introduced for buckling restrained braces （BRB） design and performance-based seismic design in the project. The analysis results showed that the structural system achieved the established performance targets and had better seismic performance under seismic action. These key problems were also discussed, such as the stability of the long cross-layer column, and how to reduce the influence of steel decorative curtain wall and main body structure.
