摘要
主要介绍广州市交通信息指挥中心结构设计的关键技术,对钢管混凝土核心柱的相关设计问题、环梁的计算及构造、菱形钢筋的设计及构造、牛腿的设计、屋顶大跨度设计、现浇混凝土空心楼盖设计等核心问题进行了详尽描述。针对剪力墙平面外抗弯承载能力的计算及锚固长度不够的问题,给出设置环梁的设计方法,并给出了设计公式。结果表明,采用单向布置的结构方案能解决荷载较大的大跨度结构受力问题;采用牛腿的转换方式能有效地解决上下错位的框架柱结构的传力问题。
Key technologies in structural design of Guangzhou Traffic Information Command Center were mainly introduced.Detailed descriptions on some major problems in designing were provided such as the design of concrete-filled steel tubular core column,calculation and construction of the circular beam,design and construction of the diamond steel bar,design of bracket,design of large-span roof as well as design of cast-in-situ concrete hollow floor. The design method and the design formula of setting circular beam were given for the calculation of the lateral flexural bearing capacity of shear walls and the insufficient anchorage length. The results show that the structure scheme of unidirectional layout can solve the force problem of large-span structure with large load. The method of bracket conversion can effectively solve the force transmission problem of the frame column structure with upper and lower dislocation.
