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。
In order to study the seismic behavior of steel frame-anti-lateral structure under the action of floor load, the single-span single-shell-solid nonlinear finite element model was established by using ABAQUS finite element software. The plastic damage of concrete and steel, On the basis of verifying the finite element model, the influence of vertical arrangement of anti-lateral wall, aspect ratio of anti-lateral wall and anti-lateral wall’s placement on the seismic performance of the structural system are verified. The results show that when building steel frame-SRC side-wall structure building, it is recommended to use the steel reinforced concrete side-resisting wall with a width of 1 200mm, which is arranged continuously along the vertical direction and can be flexibly arranged according to the openings of doors and windows Adjust the position of the wall.
