摘　　要：随着城市更新的推进,针对一些大型工业建筑,不仅要满足结构受力需要,而且更需满足现代城市生活功能。针对已报废停产的工业厂房皮带廊项目,为了满足城市园区交通需求,需拔除旧厂房皮带廊项目跨中的混凝土立柱。最后采用钢托梁替代原混凝土梁的方式,改变了结构传力路径,通过ANSYS进行结构受力验算,最终提出托梁换柱的加固改造方法,现场安装临时支撑千斤顶进行结构卸载,该方法不仅满足了原设计拆除部分支撑柱的要求,同时也实现了结构原状和其历史风貌保护。With the advancement of urban renewal,for some large industrial buildings,it is not only to meet the needs of structural stress,but also to meet the needs of modern urban life function.This paper focuses on the scrapped and discontinued industrial plant belt corridor project.In order to meet the transportation needs of urban parks,it is necessary to remove the concrete columns in the middle of the old plant belt corridor project.At the end of the project,steel joists were used to replace the original concrete beams,changing the load path of the structure.ANSYS was used for structural force verification,and a reinforcement and renovation method of replacing joists with columns was finally proposed.Temporary support jacks were installed on site for structural unloading.This method not only met the requirements of the original design for dismantling some support columns,but also achieved the protection of the original state and historical appearance of the structure.
