摘要
成都新世纪环球中心.中央游艺区钢结构屋盖是目前世界上建成的规模最大的横断面为半圆形的超大跨度建筑。通过对比分析,详细介绍了工程结构体系的选型过程,分析了结构的受力特点,并对一些特殊参数的取值进行说明。在结构设计阶段,根据杆件的重要性程度设定不同的控制标准,较好地兼顾了结构的安全性和经济性。对拱形结构及主次桁架+单层网壳结构体系受力特点进行了分析,可为类似工程提供参考。
The steel roof for Chengdu New Century Global Center Central Recreation Area is a super-large span structure with the biggest semicircular section in the world.Through comparative analysis,the selection of the structural system and the stress characteristics were analyzed while some special parameter values were described.Different control criteria were set according to the importance of structural members in order to consider the safety and the cost.The analysis of arch structures and primary-secondary trusses reinforced single layer reticulated shell structure provides references for the similar projects.
