两种偏心支撑钢框架受力性能对比分析

摘要

建立了空间Y型与K型偏心支撑钢框架有限元模型，对两种模型框架进行了单向加载和循环加载试验，对比分析了两种空间偏心支撑框架的屈服强度、极限承载力、侧向刚度、延性和耗能能力等方面受力性能的差异，为工程设计提供参考。%The finite element model of Y type and K type eccentrically braced steel frames are established. The one-way loading and cyclic load-ing tests on two kinds of framework. The stress performance of the model is different by comparative analysis,such as yield strength,ultimate bear-ing capacity,lateral stiffness,ductility and energy dissipation capacity and so on. The results provide the reference for the engineering design.
