［摘要］杭州某高層建筑，地上25層、地下1層，采用框架-剪力墻結構，主體結構已封頂。由于混凝土材料原因，17層柱、墻及18層梁的混凝土實際強度未達到設計要求，經專家論證，問題樓層須進行整體置換。通過設置臨時鋼支撐，分批置換混凝土豎向構件和水平構件，達到問題構件全部置換的目的，并通過了權威機構質量安全鑒定，取得了良好的經濟效益和社會效益。［關鍵詞］框架柱置換; 抱柱梁; 支撐鋼管; 分批置換中圖分類號：TU375 文獻標識碼：A 文章編號：1002-848X(2015)17-0037-03
Entire replacement design of wall and column in a high-rise building in HangzhouWang Jingmin(Zhejiang Architectural Design and Research Institute of Science, Hangzhou 310012, China)Abstract: A high-rise building in Hangzhou, which has 25 floors over ground and one floor underground, adopts frame-shear wall structure. The major structure was finished. However, for the reason of concrete material, the actual strength of column and wall in 17th floor as well as girder in 18th floor did not meet the requirements of the design. According to the examining report, the floors with problems need to be replaced entirely. By setting up the temporary steel support and replaced vertical member and horizontal member of concrete in batches, the unqualified member can be replaced entirely. The project has passed the safety appraisal of quality by authority, which achieves good economical and social benefits.Keywords: frame column replacement; hold column beam; steel tube support; replacement in batch
