［提要］ 針對虹口大酒店裙樓框架結(jié)構(gòu)抽柱改造工程，提出轉(zhuǎn)換梁、空腹桁架結(jié)構(gòu)和桁架結(jié)構(gòu)3種改造方案。對3種方案進(jìn)行了結(jié)構(gòu)內(nèi)力對比分析，結(jié)果表明，桁架結(jié)構(gòu)方案受力比較合理；同時后加結(jié)構(gòu)與原結(jié)構(gòu)連接構(gòu)造容易滿足，便于施工。可供類似大跨度、大荷載抽柱改造工程參考。

Structural Design on Column Removing of Hongkou Hotel/Chu Mingjin1,2, Sun Zhijuan3, Zhou Xingang1, Li Haifeng4(1 School of Civil Engineering，Yantai University, Yantai 264005, China; 2 Department of Civil Engineering, Tsinghua University，Beijing 100084, China; 3 Department of Architecture, Yantai University, Yantai 264005, China； 4 School of Civil Engineering, Qingdao Technology University, Qingdao 266033, China)
Abstract:Three schemes are developed in the project of column removing at Hongkou hotel,which are beam transfer structure, vierendeel truss transfer structure and truss transfer structure. The analysis and comparison of the three schemes show that the third scheme is rational in force behavior and convenient in construction, and it is adopted. The scheme may be a reference for the column removing practice in frame structure with long span and heavy load.
Keywords:removing column; scheme design; internal force analysis; scheme comparison
