湖南广电生产基地F演播厅及办公楼结构设计

Structural Design of Studio F and Office Building of Hunan TV Program Making Base

湖南广电生产基地F演播厅及办公楼主要建筑功能包括大演播厅以及漂浮于演播厅之上的办公楼层,整个结构利用建筑垂直交通单元组成8个钢支撑筒体作为抵抗竖向力和水平力主要构件,与上部漂浮办公钢桁架结合形成巨型框架结构体系;归纳了结构弹性分析的主要结构指标,计算结果满足规范和超限审查专家的要求;弹塑性时程分析结果表明,结构能够满足罕遇地震下的受力要求。采用大跨度空腹桁架、大跨度桁架转换体系较好地实现了建筑师的设计理念。运用TMD减振技术解决楼盖舒适度问题。

The major structures of Studio F and office building of Hunan TV program making base include thestudio and office floor. 8 steel tubes which hold the staircases and elevator halls being used as the vertical andhorizontal load resisting structure. This steel truss structure system is composed of 8 steel tubes and a steeltruss. Main structural index is presented. Elastic analysis results can satisfy demands of Chinese code. Elastic-plastic time-history analysis manifests that the bearing capacity of the structure meets the requirements of thestructural force. The use of the vierendeel truss and long span transfer structure realizes the design idea of thearchitect. TMD technology is applied to solve the comfort problem.
