摘要
中国石油大学(华东)体育馆屋盖结构采用单层双曲抛物面网壳形式,屋顶平面为不规则形状,近似为椭圆形。结构方案的特点是在上弦杆的同一竖直平面内设置交叉腹杆。对该工程的结构方案、主要构造、施工工艺、结构在恒载与活荷载组合作用下的受力分析等进行了介绍。工程实践表明:本工程采用的网壳结构不仅造型新颖美观,而且结构受力合理,传力明确,具有较大的安全储备。
Hyperbolic paraboloid shell structure was used in the roof of China University of Petroleum（East China）Gymnasium,which had irregular shape,near to the elliptical shape.In particular,this structure also set up diagonal web members on the vertical plane of upper chords to connect with upper chords and vertical bars.In this paper,an introduction to the shell is made from the structure concept,major structure,construction technology,the forces under loading combination of dead load and live load,and so on.The engineering practice shows that the structure of this project has aesthetic appearance,appropriate mechanical property,and greater safety margin.
