［摘要］重慶新華國際大廈局部托柱轉(zhuǎn)換體系承擔了上部54層的荷載，為追求經(jīng)濟、合理的設(shè)計方案，對鋼筋混凝土深梁、型鋼混凝土組合梁、空腹桁架、疊層空腹桁架、斜腹桁架、疊層斜腹桁架6種方案進行了試算和比選，最終擬采用型鋼混凝土空腹桁架方案。介紹了空腹桁架方案的受力分析、構(gòu)造措施等，并對分析模型、計算參數(shù)、桿件設(shè)計等問題進行了探討。

Abstract:Xinhua International Building located in Chongqing requires a frame column underpin transfer system which supports large load from 54 floors. In order to discover an economical and rational way to design the project, 6 schemes including deep beam, steel reinforced concrete composite beam, vierendeel truss, two\|storey vierendeel, diagonal truss and two\|storey diagonal truss were discussed. Vierendeel truss with steel reinforced concrete composite members was adopted. Mechanical behaviors and construction measures of the vierendeel truss were introduced, and the analysis model, parameters, member design methods and etc. were also investigated.
Keywords:super high-rise building; vierendeel truss; transfer system; steel reinforced concrete composite member
