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 anaIysis is focused on the seIection puting modeI and foundation modeI, as weII as the structuraI
optimization design of Iarge-span prestressed Iatticed grid roof structure and partIy two-story Iarge-span prestressed
reinforced concrete sIab system with some significant resuIts obtained. The main characteristics of the structure are as
foIIows. FirstIy, the prestressed Iatticed grid roof structure is connected with upIift piIes through puII rods on two sides
of the structure to form a seIf-baIanced system so as to reduce the moment and shear of supporting structure; secondIy, the
seIection of the boIt hinge joint at the bottom of steeI coIumns is the key to structur
