惠州市会展中心主体结构设计研究

Structural design research of the main structure of Huizhou Conference and Exhibition Center

惠州市会展中心是惠州市重点项目"三馆一场"之一,该工程为大型复杂展览建筑,上部主体结构主要分为两个部分,展厅和波浪型屋盖。展厅采用钢筋混凝土筒体+钢管混凝土钢框架混合结构体系,屋盖采用单层柱面钢网壳结构,单层网壳屋盖通过人字形斜撑支承在剪力墙端柱上。重点介绍了展厅结构及屋盖单层网壳结构的构成,对整体结构进行了多工况的变形受力性能分析,对典型节点及复杂节点进行了精细的有限元分析,阐述了会展结构的一般设计方法,得到了一些设计经验。

Huizhou Conference and Exhibition Center is one of important building of urban planning of ＇ three pavilions and one stadium＇. The project is a huge and complex exhibition building. The upper structure is composed of two parts ： exhibition hall and wave-shape roof. Reinforced concrete cylinder＋ CFST frame hybrid structural system is adopted in the exhibition hall. Cylindrical single-layer latticed shell structure is adopted in roof. The latticed shell is supported by chevron braces which is connected with the end column of the shear wall. The structure constitution of exhibition hall and the latticed shell roof were introduced. Deformation and mechanical property were analyzed of the whole assembly structure under multiple working conditions. Detailed analysis of the finite element entity was carried out on common and complex nodes. The common design method of conference and exhibition Structure was introduced and some design experience was obtained.
