| 摘 要： | 世博会城市最佳实践区中部展馆系列由多组老厂房改建而成,各单体结构建筑造型新颖独特。结构设计中,通过对单层厂房结构的抗侧力体系的转换,取消了落地柱间支撑,满足了建筑功能需求。部分展馆采取新老结构脱开的处理方式,避免节点连接困难,简化结构抗震体系,提高了结构抗震性能。采用V形柱钢框架形成新建结构,计算结果表明,V形柱钢框架结构扭转效应显著。通过设置纵向支撑,降低了结构扭转效应,整体计算结果满足规范要求。基于闭口薄壁杆件扭转理论,对V形柱的约束扭转计算方法进行分析,应力计算结果满足规范要求。

| Abstract: | The midst pavilions in the urban practice area of EXPO 2010 consist of several reconstructed factory buildings.Every hall has novel architectural form and a unique structure style.Through transforming the longitudinal structure for resistance to lateral force,the intercolumn braces were canceled,the requirement for the large space was meet.In some pavilions,the new structure was isolated from the original structure.The V-shape steel frame was applied for the new one.The calculation results shows the signifi... |
