中文摘要：

针对偏心支撑框架体系耗能梁段震后修复难度大、经济性差的问题,提出了采用剪切钢板阻尼器作为可更换耗能梁段的偏心支撑结构体系。采用ABAQUS有限元软件对国外已完成的可更换耗能梁段偏心支撑试验进行结构分析,验证了有限元建模的正确性,分别对不同腹板宽厚比、腹板钢材屈服强度、腹板加劲肋设置情况下的剪切钢板阻尼器K型、D型偏心支撑钢框架进行结构分析,研究了耗能梁段的变形机制、滞回耗能能力以及局部失稳、局部破坏形态。分析结果表明：剪切钢板阻尼器作为耗能梁段是可行的,阻尼器首先发生屈服,起到了主要耗能作用,在实际工程应用中建议剪切钢板阻尼器腹板宽厚比宜小于30,腹板钢材宜采用软钢及低屈服点钢,采用加劲肋来保证阻尼器不发生平面外屈曲。

英文摘要：

In the light of the problems that difficult to repair and the problem of poor economy of active beam link, the author come up with a new scheme using steel shear panel damper for active beam link in this paper. Using finite element analyze software ABAQUS to analyze different width-thickness ratios of panel, yield point of steel of panel, setting of stiffeners of panel in a steel frame with steel shear panel damper. Analyzing the deformation mechanism, hysteretic energy dissipation capacity, local buckling and local damage of damper. The simulation result shows that scheme using steel shear panel damper of active beam link is feasible, steel shear panel damper yields firstly and plays a major role in energy dissipation. In practical engineering the author suggests that the width-thickness ratio of panel may be less than 30, the steel of panel uses mild steel, setting stiffeners to prevent the out of plane buckling.
