凉都体育中心包括体育场和体育馆,下部采用钢筋混凝土框架结构,体育场罩蓬采用立体管桁架结构,体育馆屋盖采用网壳结构。体育场下部超长混凝土采用底部楼层分缝而上部楼层连接的方法控制温度应力,对体育场屋盖长悬挑钢结构和体育馆屋盖网壳结构进行了刚性模型和数值模型的风洞试验以确定风荷载计算参数。通过MIDAS软件对屋盖结构体系进行受力、变形、模态和屈曲分析,根据计算结果对体育场加设了屋面平面桁架支撑,对体育馆采用了局部三层网壳结构,改进了体育场和体育馆屋盖结构受力体系,优化了结构性能。基础设计采取了有效措施解决了岩溶强发育地区桩基设计的困难。
Liangdu Sports Center includes stadiums and gymnasiums, the lower part adopts the reinforced concrete frame structure, the stadium canopy adopts the three-dimensional tube truss structure, and the gymnasium roof adopts the reticulated shell structure. The lower part of the stadium uses the method of controlling the temperature stress by means of the connection of the upper floor and the upper floor. The rigid-model and numerical model wind tunnel tests are carried out on the long-suspended stadium steel structure and the reticulated shell structure of the stadium to determine the wind Load calculation parameters. Through the software MIDAS, the roof structure system was subjected to force, deformation, modal and buckling analysis. Based on the calculation results, a roof trussed truss was added to the stadium, and a partial three-layer reticulated shell structure was adopted for the stadium to improve the stadium and gymnasium Cover the structure of the force system, optimizing the structural performance. The basic design has taken effective measures to solve the difficulties in pile foundation design in areas with strong karst development.
