［摘要］鋼-混凝土混合結(jié)構(gòu)能充分發(fā)揮鋼結(jié)構(gòu)及混凝土結(jié)構(gòu)兩種材料的優(yōu)點(diǎn)，具有良好的受力性能，可較好地滿足建筑造型要求，在實(shí)際工程中有眾多的應(yīng)用。銀川火車(chē)站站房即為鋼-混凝土混合結(jié)構(gòu)，且結(jié)構(gòu)體系及受力性能較為復(fù)雜。針對(duì)此類(lèi)結(jié)構(gòu)分析設(shè)計(jì)中所遇到的問(wèn)題，基于整體結(jié)構(gòu)建模分析，采用多軟件多方法的分析手段，以確保結(jié)構(gòu)分析結(jié)果的準(zhǔn)確性和可靠性。另外還探討了混合結(jié)構(gòu)中鋼結(jié)構(gòu)與混凝土結(jié)構(gòu)的相互影響及連接支座參數(shù)的確定的問(wèn)題。
［關(guān)鍵詞］鋼-混凝土混合結(jié)構(gòu)；雜交結(jié)構(gòu)；振型阻尼比；鋼結(jié)構(gòu)設(shè)計(jì)；連接支座

Yu Donghui, Bi Dayong, Ao Xiaolei, Lu Guangqing(Beijing Institute of Architectural Design, Beijing 100045, China)
Abstract:Steel-concrete hybrid structure, which can fully exert the advantages of the two kinds of structures and can meet the requirements of building style, has numerous applications in actual engineering for the requirement of architectural function and modeling. Yinchuan Railway Station is the steel-concrete hybrid structure, and the structure and mechanics properties are complex. To solve the problems in hybrid structural design,  multiple softwares and methods were used in design with overall analysis model. The accuracy and reliability of the structural analysis are ensured. The interaction between steel structure and concrete structure in hybrid structure is also discussed.
Keywords:steel-concrete hybrid structure; modal damping ratio; steel structure design; bearing stiffness setting
