重庆某剧院抽柱转换加固方案

摘要

重庆某剧院结构主体实施完毕后因建设方对使用功能提出了更高的要求，增加了舞台两侧的侧台功能，需要抽取4颗柱子。该4颗柱子支承着大跨度的屋面大梁，改造设计难度很大。该文针对性地提出了五种加固改造方案，通过多角度比选，确定了适合该工程的加固改造方案，最后基于选定的加固改造方案给出了合理而详尽的施工步骤。%The body of a theatre structure in Chongqing has been completed, but the construction party proposes higher requirements for its utilization functions, so four columns are to be withdrawn for side stage functions. The four columns are supporting the large-span beam, so the reconstruction de-sign is quite difficult. This paper presents five reinforcement schemes and, through careful comparisons, a suitable one is selected, with detailed construc-tion steps given.
