［摘要］上海城市名人酒店（原沪西商业大厦）改建工程位于曹家渡的中心区域，改建前的上海城市名人酒店建于1994年，为一幢集酒店、商业、电影院功能于一体的高层建筑，地下2层，地上28层（含技术层）。由于原来结构的设计遵循较早的抗震规范，加上结构需要部分拆建和改建，对裙楼拆除和改建范围四周的以下柱子和剪力墙采用外包混凝土的方式进行加固。分析结果表明，加固后结构的承载力有较大程度的提高。抗震分析和现有结构的房测报告结果表明，名人酒店的改建方案是可行的。

Abstract: Reconstruction project of Shanghai Celebrity City Hotel (formerly Huxi commercial buildings) is located in the central region of Caojiadu. Shanghai Celebrity City Hotel before the reconstruction was built in 1994, which is a set of hotel, commercial, movie theater functions in one high-rise building, 2 floors underground and 28 floors overground (including technical floor). Because of the design of the original structure according to seismic code earlier and the need of demolition and reconstruction structure, skirt building demolition and reconstruction of the podium range around the following columns and shear walls were reinforced by concrete way. The analysis results show that the bearing capacity of the reinforced structure is greatly improved. Room measurement report the results of seismic analysis and existing structures suggest that celebrity hotel renovation is feasible. Seismic analysis and the existing structure of the housing survey report shows that the Shanghai  Celebrity Hotel renovation program is feasible.
