| 摘 要： | 本文介绍了广东现代国际展览中心结构设计。重点论述该结构体系的计算模型处理、基础选型以及大跨度预应力空间网架和局部二层大跨度预应力钢筋混凝土楼盖结构体系的优化设计,得到一些有意义的结论。本结构设计的主要特点是:(1)上部预应力网架结构通过两侧的拉杆锚在桩上而形成一个自平衡体系,从而减小支承结构柱的弯矩和剪力;(2)钢柱柱脚铰接的选择对于优化结构受力非常关键;(3)通过在钢柱沿建筑长方向上设置预应力拉索来保证钢柱在该方向上的稳定性。

| Abstract: | The analysis is focused on the selection of computing model and foundation model, as well as the structural optimization design of large span prestressed latticed grid roof structure and partly two story large span prestressed reinforced concrete slab system with some significant results obtained. The main characteristics of the structure are as follows. Firstly, the prestressed latticed grid roof structure is connected with uplift piles through pull rods on two sides of the structure to form a self balanced system so as to reduce the moment and shear of supporting structure;secondly, the selection of the bolt hinge joint at the bottom of steel columns is the key to structural optimized design; thirdly, the longitudinal stability of steel columns is secured by prestressing cables bracings. |
