摘　　要：本文在吸取国内外学者有关研究的基础上,开发研制了一种新型的耗能器———软钢支撑式阻尼器。这种耗能器的优点是耗能区域明确,受拉和受压均能实现承载全截面屈服,本文采用Ansys软件中Solid单元对该耗能器的滞回性能和屈曲性能进行分析。研究结果表明,该耗能器耗能能力强,且变形主要集中在预设的工作区域内。Base on the current state of research and application home and abroad, a new conformation type of mild steel buckling-restrained brace suitable to energy dissipater is developed. The outstanding advantage is the certain zones of dissipation and the all section yield in both tension and compression without buckling. The performance of hysteresis and buckling stability is analyzed using ANSYS programs through the element of solid .The results reveal the better energy dissipating and the previous designed deformation displacemant.
