西宁海湖体育中心游泳馆结构设计

Structural design of natatorium in Haihu Sports Center in Xining

介绍了西宁海湖体育中心游泳馆的上、下部结构选型及钢屋盖体系布置,建立了钢屋盖单体模型和上、下部结构整体模型,并对两种模型在水平和竖向荷载作用下的内力和变形进行了分析比较。介绍了风洞试验、风荷载取值方法及大跨门式刚架柱脚连接构造措施的比较分析,为类似工程提供了工程实际案例。

The structural system selection of upper and lower parts and steel roof system layout of natatorium in Haihu Sports Center in Xining were introduced.The single model of steel roof and the overall model of the upper and lower structure were established,and the internal forces and deformations of two models under the horizontal and vertical forces were analyzed and compared.The comparative analysis of wind tunnel test,wind load determination method and connection construction measures of large-span portal frame column bases were introduced.The engnieering case is provided for this kind of projects.
