摘要: 近年來,隨著建筑專業(yè)需求的增加,多塔連體高層結(jié)構(gòu)越來越多,在特定條件下,強連體結(jié)構(gòu)是必須選擇的連體結(jié)構(gòu)形式. 對于復(fù)雜多塔強連體結(jié)構(gòu),剛度是選擇連體結(jié)構(gòu)形式的根本依據(jù),包括單體結(jié)構(gòu)的剛度、連接體結(jié)構(gòu)的剛度以及整體結(jié)構(gòu)的剛度. 結(jié)構(gòu)設(shè)計應(yīng)根據(jù)剛度的需求選擇合適的連體部位、連接體結(jié)構(gòu)類型和連接方式,不應(yīng)盲目追求提高剛度. 分析了連體高層結(jié)構(gòu)的受力特點,提出連體高層結(jié)構(gòu)設(shè)計的關(guān)鍵問題和設(shè)計思路,并以一個四塔高位連體實際工程為例,從整體結(jié)構(gòu)布置、連接體設(shè)計、連接體與塔樓連接的復(fù)雜節(jié)點設(shè)計、抗震性能化設(shè)計、結(jié)構(gòu)全生命周期分析等多方面總結(jié)復(fù)雜多塔連體高層結(jié)構(gòu)設(shè)計的技術(shù)難點和設(shè)計對策.
關(guān)鍵詞: 多塔連體; 強連接; 連體桁架; 剛度需求; 鋼節(jié)點

Abstract: In recent years, leading by architect,the demand of multi-tower connected high-rise structures is increasing,under certain conditions, the strong conjoined structure is the conjoined structure form that must be chosen. For thecomplex multi-towe strong conjoined structures, the stiffness is the fundamental condition for selecting the type ofconnecting structure. The stiffness includes the stiffness of the single structure, the stiffness of the connecting structure andthe stiffness of the whole structure. The structural design should choose the appropriate conjoined parts, connectingstructure type and connection mode, according to the requirement of stiffness,and should not blindly seek to improve thestiffness. The mechanical characteristics of the connected high-rise structure were analyzed, and the key problems anddesign ideas of the connected high-rise structure design were proposed, and the technical difficulties and designcountermeasures of complex multi-tower conjoined high-rise structure design were summarized from various aspects such asoverall structure arrangement, connecting structure design, complex joint design of connecting structure and towerconnection, seismic performance-based design, and structural whole life cycle analysis by taking a four-tower high-riseconjoined actual project as an example.
Keywords:multi-tower conjoined structure; rigid connection; conjoined truss; stiffness requirement; steel joint
