某体育中心结构设计

Structural Design of a Sports Center

详细介绍了某体育中心的结构设计。针对项目用地条件,工程采用了先进、同时对施工吊装设备要求较低的索承结构体系。体育馆、训练馆和游泳馆充分利用周圈布置的环梁和V撑为索结构屋盖提供水平和竖向刚度;大跨度屋盖刚度由索结构体系自身的预张索力提供。根据建筑造型以及功能要求,场馆下部混凝土采用框架结构、预制看台板体系,屋盖钢结构分别采用索穹顶、单层索网、轮辐式双层索网以及张弦梁等索承结构体系,达到了技术先进、安全适用、经济合理、美观以及高效的材料利用率的目标,为大跨度索承结构体系在强台风地区的应用起到了一定的推动作用。

Introduces the structure design of a sports center in detail.According to the land conditions of the project,the advanced cable supported structure system with low requirements for construction hoisting equipment is adopted in the project.Gymnasiums,training halls and natatoriums make full use of ring beams and V-braces arranged around the perimeter to provide horizontal and vertical stiffness for cable structure roofs.The stiffness of long-span roof is provided by the pretensioned cable force of the cable structure system itself.According to the architectural modeling and functional requirements,the lower concrete of the venue adopts a frame structure and a prefabricated stand plate system,and the steel structure of the roof adopts cable supported structural systems such as cable dome,single-layer cable net,spoke type double-layer cable net,and beam string,achieving the goal of advanced technology,safe application,economic rationality,beauty,and efficient material utilization,It has played a certain role in promoting the application of long-span cable supported structures in strong ty‐phoon areas.
