［摘要］沈陽(yáng)市府恒隆廣場(chǎng)塔樓一為東北地區(qū)最高的建筑之一，采用SAP2000軟件對(duì)其皇冠結(jié)構(gòu)及二次結(jié)構(gòu)進(jìn)行靜力分析，采用ABAQUS軟件對(duì)擦窗機(jī)支架與皇冠外弦桿受力最大的節(jié)點(diǎn)進(jìn)行有限元分析。分析結(jié)果表明，皇冠結(jié)構(gòu)及二次結(jié)構(gòu)構(gòu)件的應(yīng)力比、變形及整體穩(wěn)定性均滿足相應(yīng)規(guī)范要求；根據(jù)強(qiáng)節(jié)點(diǎn)弱構(gòu)件的原則，整體計(jì)算結(jié)果也滿足強(qiáng)節(jié)點(diǎn)設(shè)計(jì)要求。通過(guò)精確建模及詳細(xì)的計(jì)算分析可知，結(jié)構(gòu)體系的合理布置是保證整個(gè)皇冠結(jié)構(gòu)順利竣工的關(guān)鍵，本工程的鋼結(jié)構(gòu)施工達(dá)到預(yù)期，并取得了良好的經(jīng)濟(jì)效益。

Abstract:The No.1 tower building of Henglong City Plaza in Shenyang is one of the highest buildings in the Northeast China. SAP2000 software was used to conduct static analysis on the crown structure and its secondary structure, and ABAQUS software was used to conduct finite element analysis of bracket of the window wiping machine and joints of crown′s exterior chords with the largest stress. The analysis results show that the stress ratio, deformation and overall stability of crown structure and its secondary structure meet the corresponding requirements of codes; according to the principle of strong joint and weak component, the overall calculation results also meet the design requirements of strong joint. The precise modeling and detailed calculation and analysis show that the reasonable layout of structural system is the key to ensure the smooth completion of the crown structure, the steel structure construction of the project meet expectations and achieves good economic benefits.

Keywords:crown structure; bracket of the window wiping machine; secondary structure; key joint
