［摘要］采用有限元分析軟件SAP2000分析了淮北礦業(yè)辦公中心主樓連體結(jié)構(gòu)樓面混凝土澆筑、臨時(shí)支撐拆除等施工過程中型鋼混凝土空腹桁架及其臨時(shí)支撐體系的應(yīng)力和變形。計(jì)算結(jié)果較準(zhǔn)確地反映了各施工階段施工荷載作用下結(jié)構(gòu)的變形和內(nèi)力分布，表明桁架支撐體系合理，為施工方案及實(shí)時(shí)監(jiān)測提供理論依據(jù)。

Abstract:Finite element analysis software SAP2000 was used to analyze the stress and deformation of steel-reinforced concrete open-web truss and its brace system during the construction of Huaibei Mining Office Center Building. The results can accurately reflect the structure deformation and inner force distribution under the construction loads in every construction stage. It indicates that the arch-truss braced system is verified reasonable， which can provide theoretical basis for the construction scheme and real-time monitoring.
Keywords:construction simulation; open-web truss; connected structure; steel-reinforced concrete
