［摘要］为了研究钢框架-抗侧力结构在楼面荷载作用下的抗震性能，采用ABAQUS有限元软件建立单层单跨壳-实体非线性有限元模型，考虑了混凝土与钢材的塑性损伤以及加载的随动强化准则，在验证有限元模型的基础上，考察抗侧力墙体沿竖向布置方式、抗侧力墙体高宽比以及抗侧力墙体布置位置对结构体系抗震性能的影响。研究结果表明：在建造钢框架-型钢混凝土抗侧力墙结构房屋时，建议选用宽度为1 200mm的型钢混凝土抗侧力墙体，且沿竖向连续布置，并可根据门窗洞口的布置，灵活调整墙体的位置。［关键词］钢框架-型钢混凝土抗侧力墙结构; 抗震性能; 楼面荷载作用; 有限元分析中图分类号：TU392.1 文献标识码：A 文章编号：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
