摘　　要：结合EBF的工作原理,建立了两层Y型耗能支撑模型,并以ANSYS10.0为工具,研究其在低周循环荷载作用下的性能。在研究中,以腹板高度、腹板厚度为参数,研究这些参数的变化对耗能段耗能性能的影响,并对Y型偏心支撑钢框架提出设计建议。Based on the working principle of EBF, the numerical models of double storey Y-eccentrically braced steel frame are established, and the anti-force performance is analyzed under cyclic loads by ansyslO.O. In the research, the height of the web and the thickness of the web are taken as the parameters, and the influence of the parameters on the behavior of H-shaped section links are studied. In conclusion, the proposal for designing Y type eccentrically braced steel frames is made.
