［摘要］為了研究鋼框架-抗側(cè)力結(jié)構(gòu)在樓面荷載作用下的抗震性能，采用ABAQUS有限元軟件建立單層單跨殼-實(shí)體非線性有限元模型，考慮了混凝土與鋼材的塑性損傷以及加載的隨動(dòng)強(qiáng)化準(zhǔn)則，在驗(yàn)證有限元模型的基礎(chǔ)上，考察抗側(cè)力墻體沿豎向布置方式、抗側(cè)力墻體高寬比以及抗側(cè)力墻體布置位置對(duì)結(jié)構(gòu)體系抗震性能的影響。研究結(jié)果表明：在建造鋼框架-型鋼混凝土抗側(cè)力墻結(jié)構(gòu)房屋時(shí)，建議選用寬度為1 200mm的型鋼混凝土抗側(cè)力墻體，且沿豎向連續(xù)布置，并可根據(jù)門窗洞口的布置，靈活調(diào)整墻體的位置。［關(guān)鍵詞］鋼框架-型鋼混凝土抗側(cè)力墻結(jié)構(gòu); 抗震性能; 樓面荷載作用; 有限元分析中圖分類號(hào)：TU392.1 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)04-0027-07
Finite element analysis on seismic behavior of steel framesteel reinforced concrete lateral resistance wall structureGuan Yu(School of Civil Engineering, Chang′an University, Xi'an 710061, China)Abstract:In order to study the seismic behavior of steel frame-lateral resistance structure under floor load action, the nonlinear one bay and one story shell-entity finite element model was established by ABAQUS finite element software. The finite element model considered plasticity damage of concrete and steel as well as kinematic hardening criterion during loading process. On the basis of verifying finite element model, the influences of vertical arrangement of lateral resistance wall, the height-width ratio of lateral resistance wall and arrangement position of lateral resistance wall on the seismic performance of the structural system were investigated. The results show that during the construction of steel frame-steel reinforced concrete lateral resistance wall structure buildings, steel reinforced concrete lateral resistance wall with width of 1 200mm was suggested to choose, and the wall should be arranged continuously along the vertical direction. Moreover, the wall should be arranged according to the openings of windows and doors, and the position of the wall should be adjusted flexibly.Keywords:steel frame-steel reinforced concrete lateral resistance wall structure; seismic behavior; floor load action; finite element analysis
