［摘要］河北聯(lián)合大學(xué)圖書館主樓為現(xiàn)澆鋼筋混凝土框架-剪力墻結(jié)構(gòu)體系，上部結(jié)構(gòu)采用超大跨度桁架和大跨度型鋼混凝土梁進(jìn)行轉(zhuǎn)換，介紹了圖書館主樓的結(jié)構(gòu)設(shè)計(jì)特點(diǎn)及采取的相關(guān)措施。通過YJK和PMSAP兩種軟件進(jìn)行計(jì)算，詳細(xì)分析了轉(zhuǎn)換桁架的形式、節(jié)點(diǎn)連接方式以及施工順序?qū)χ苓厴?gòu)件和整體結(jié)構(gòu)的影響。結(jié)合施工深化設(shè)計(jì)優(yōu)化了轉(zhuǎn)換桁架的關(guān)鍵節(jié)點(diǎn)構(gòu)造，并根據(jù)實(shí)際受力和施工情況將桁架設(shè)計(jì)成上下弦桿為型鋼混凝土構(gòu)件，中弦桿、斜撐和豎桿為純鋼構(gòu)件的形式，對今后的轉(zhuǎn)換結(jié)構(gòu)設(shè)計(jì)提供一定的借鑒意義。［關(guān)鍵詞］河北聯(lián)合大學(xué)圖書館; 大跨度轉(zhuǎn)換桁架; 結(jié)構(gòu)設(shè)計(jì); 施工模擬; 節(jié)點(diǎn)優(yōu)化中圖分類號(hào)：TU318+.2 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)03-0070-06
Structural design of main building of Hebei United University LibraryZhang Jinhai, Wang Xiang′an, Wang Heng, Shan Yukun, Wei Qiang, Liu Yanru, Meng Fanhui(Architectural Design and Research Institute of Tianjin University, Tianjin 300073, China)Abstract:The reinforced concrete frame-shear wall structure system is adopted in main building of Hebei United University Library. The super-long span truss structure and long span steel reinforced concrete beam are used for the transformation of upper structure. The design characteristics and relevant measures of the main building were introduced. The transfer truss form, node connection method and the effect of construction sequence on surrounding components and the overall structure were analyzed by the programs of YJK and PMSAP. The key nodes of transfer truss were optimized though deepening the design. According to the actual force and construction condition, the transfer truss was designed of the combination that the up and down chord using steel reinforced concrete and the middle chord, diagonal brace, steel vertical column using pure steel, which provides reference for the design of transfer structure in the future.Keywords:Hebei United University Library; long span transfer truss; structural design; construction simulation; node optimization
