半刚性连接钢框架-轻钢龙骨隔墙体系抗侧力性能研究
|
摘要
提出半刚性连接钢框架与轻钢龙骨隔墙组合结构体系,研究其抗侧力性能。对变化轻钢龙骨隔墙形式以及梁柱节点连接形式的5个试件进行低周往复加载试验,得到其滞回曲线、骨架曲线、承载力、初始刚度以及结构耗能性能,对比各组试件的破坏特征,分析轻钢龙骨隔墙以及钢框架梁柱连接形式对结构的抗侧刚度、承载力、延性及滞回性能的影响。研究结果表明:钢框架与轻钢龙骨隔墙共同工作,半刚性节点对结构耗能性能贡献较大,结构具有较好的延性;龙骨节点加强对结构的承载力和初始刚度影响不大,但可提高结构的延性和滞回性能;龙骨外侧添加的蒙皮可增加结构刚度,大幅提高结构的承载力。
In this paper,the semi-rigid steel frame with light steel keel wall was proposed.Lateral force resistance behavior of this kind of structure system was discussed.Hysteretic tests of five groups of different forms of steel frame with light steel keel wall were done.The test parameters were the beam-column connection and the form of light steel keel wall.Hysteretic curves,skeleton curves,bearing capacity,initial stiffness and energy dissipation capacity of the structure system were obtained.Failure characteristic of each specimen was discussed.The influences of the light steel keel partition wall and steel frame connection form on the lateral stiffness of the structures,bearing capacity,ductility and hysteretic performance were analyzed.The research results show that the semi-rigid connection contributes a great deal to the energy dissipation capacity of the structure system.The steel frame and light steel keel partition wall can work together.The structure has a good ductility.The iron skin added to the outside surface of keel wall can help increases the lateral stiffness and bearing capacity of the structure.
