| 摘 要： | 北京某钢框架-支撑体系多层钢结构商场改为大型超市,要求增加二、三层楼面活荷载,取消首层和二层柱间支撑。加固改造中,通过原钢柱外包混凝土形成钢骨柱和新增纵向钢筋混凝土框架方法,将钢框架-支撑体系改为双向框架体系,较好地达到了预期目的。

| Abstract: | A multilstory steel emporium with lateral brace in Beijing is reconstructed a large supermarket,which requires to increase live load of the 2nd and 3th floor, takes out brace in 1st and 2nd floor, Steel frame with lateral brace system is reconstructed bidirectional frame system via wrapping concrete out of the original steel column to form SRC column adding longitudinal RC frame,which obtain anticipative purpose. |
