（北京科技大學土木系，北京 100083）[摘要] 對一實際的鋼管混凝土結(jié)構(gòu)進行三維有限元地震反應分析。在有限元分析過程中，分別采用剛度等效法和鋼管混凝土統(tǒng)一理論法進行建模。隨后對結(jié)構(gòu)進行模態(tài)分析和時程反應分析，并比較了兩個有限元模型計算結(jié)果的差別，可供相關(guān)工程設(shè)計參考。[關(guān)鍵詞] 鋼管混凝土; 有限元; 地震反應分析中圖分類號：TU352 文獻標識碼：A 文章編號：1002-848X(2013)S2-0464-03Seismic response analysis of concrete-filled steel tubes structuresGuo Yong, Pan Danguang(Department of Civil Engineering, University of Science and Technology Beijing, Beijing, 100083, China)Abstract: Seismic response analysis of a CFST (concrete-filled steel tubes) structures is completed by using space FEM (finite elements method). During the FEM analysis, the modals are required according as section conversion method and CFST united theory respectively. Then mode analysis and transient analysis are calculated. At the same time, the difference of results between the two modals is compared. The results have referential value for similar engineering.Keywords: concrete-filled steel tube; FEM; seismic response analysis
