The study that comprehensive and systematic analyze the factor of links length, thickness of links flange, distance of links rib, thickness of links rib and angle of brace to be changed affect energy-dissipation capacity of D shape and K shape eccentrically braced steel frames have been some studied before. This paper fills the black in the filed factor of high-span ratio, brace stiffness and brace-to-beam connections to be changed affectenergy-dissipation capacity of D shape and K shape eccentrically braced steel trames and any factor to be changed affect energy-dissipation capacity of Y shape eccentrically braced steel frames.

对耗能梁段的长度、耗能梁段腹板的厚度、耗能梁段翼缘的厚度、耗能梁段加劲肋的间距、耗能梁段加劲肋的厚度、支撑的夹角等因素的改变对D形、K形偏心支撑钢框架耗能的影响，前人已有一些研究，本文对这些因素的影响进行了全面系统的分析，完善了理论分析的不足；而结构高跨比、支撑刚度、支撑与梁的连接形式等因素对D形、K形偏心支撑钢框架破坏机理的研究以及各种因素对Y形偏心支撑钢框架破坏机理的影响，则很少有人涉及，本文对此也进行了深入系统的分析，填补了这一研究空白。
