| 摘 要： | 西藏会展中心工程地处高海拔、低含氧量的拉萨地区,屋盖空间形状复杂,高度、跨度大及杆件数量较多,施工中开发和应用了屋盖外围部分采用组合单元吊装、屋盖内部部分采用整体提升技术。通过非线性施工过程分析验证该施工技术的可行性,对屋盖桁架进行同步和不同步提升状态结构分析、提升支架受力分析,为结构的安全施工提供理论依据。

SIMULATION OF THE CONSTRUCTION PROCESS OF THE STEEL ROOF OF TIBET CONVENTION AND EXHIBITION CENTER |
| |
| Abstract: | Tibet Convention and Exhibition Center project is located in high altitude,low oxygen levels in Lhasa area,with the complexity of roof shape,height,large span and lots of pipes,a construction plan of the outer part of the roof lifting by combining unit,the internal part of roof by integral lifting technology is established.Nonlinear finite element analysis of the construction process verified the feasibility of this technique.Analyses were performed for synchronized hoisting and unsynchronized hoisting,the forces of the lifting frame were then analyzed to provide theoretical support for the safety of the construction. |
