摩擦型耗能支撑钢框架结构抗侧力性能研究

将某六层高级住宅作为研究对象,设计了2个单跨两层钢框架结构试件,将其中一个试件嵌入摩擦型耗能支撑,另一个试件无嵌入,为普通试件。给出选用钢材的力学性能指标,介绍了试件的加载方法。对摩擦型耗能支撑钢框架试件的破坏情况进行分析。将侧移角达到1/50看作钢结构的破坏状态,对摩擦型耗能支撑钢框架结构和一般钢框架结构试件的抗侧承载力、抗侧刚度、延性、应力分布与变形进行测试。结果表明,摩擦型耗能支撑钢框架结构有很高的抗侧力性能。

Study on lateral force resistance of friction energy dissipation braced steel frame structure

In this paper, a six story high-rise residential building was designed as the research object, and 2 single span steel frame specimens were designed, one of which was embedded into the friction energy dissipation brace, and the other one was not embedded in the. The mechanical properties of the steel are introduced, and the loading method is introduced. The failure of the steel frame with friction energy dissipation brace is analyzed. The lateral displacement angle of 1/50 is considered as the destruction state of the steel structure.The lateral bearing capacity, lateral stiffness, ductility, stress distribution and deformation of friction type energy consumption steel-frame structure and general steel-frame structure are tested. The results show that the friction energy dissipation braced steel frame structure has high lateral resistance.
