摘要
世博中心是2010年上海世博会永久场馆之一,根据建筑特点抗侧力体系选用钢框架支撑结构体系。采用基于性能的消能减振抗震设计方法,在结构关键部位设置防屈曲耗能支撑(简称BRB),从而提高结构的抗震性能,降低主体结构的用钢量。结构计算结果表明:合理的结构布置可以解决结构平面超长、大空间多、质量分布不均匀等设计难题。结构设计进行了框架柱的计算长度确定、施工阶段模拟、楼面活荷载不利布置等专项分析。结构设计与绿色建筑理念相结合,既满足可持续发展和低碳建筑要求,也符合"城市,让生活更美好"上海世博会的主题。
The Expo Center,at the 2010 Shanghai Expo site is one of the major permanent projects serving as conference and exhibition center during the Expo period.This paper describes the steel braced frame system,which was designed reasonably according to the architectural requirements.Based on performance-based energy dissipating and vibration isolating design concept,buckling restrained braces（BRB） are applied in the critical positions to improve the seismic performance and reduce the steel consumption.Analytical results indicate that reasonable structural design can solve the problems such as extra building length,uneven mass distribution and large space.The specific analyses on column effective length,staged construction analysis and live load distribution are adopted.In addition,the structural design combines with the philosophy of green building and caters for the Expo theme of Better City,Better Life as well.
