【摘要】 根据框架填充墙的破坏情况和粘弹性阻尼器耗能机理,提出了改善框架填充墙抗震性能的新方案—新型框架阻尼填充墙。采用ABAQUS有限元软件对新型框架阻尼填充墙进行了仿真分析。结果表明:新型框架阻尼填充墙与普通框架填充墙相比,混凝土框架、钢筋、墙体的最大应力都有所降低,耗能系数有所提高。新型阻尼墙具有良好的耗能能力,改善了传统填充墙框架在地震中的抗震性能,在地震区的框架结构中有良好的应用价值和开发前景。更多还原

【Abstract】 Based on the damages of infilled-frame structure in the earthquake and the energy dissipation mechanism of visco-elastic damper,a new damping wall is proposed.The ABAQUS software is used to simulate and analyze the new damping wall.The results indicate that both the maximum stress and the initial stiffness of the framework,reinforced steel and infilled-wall are reduced,and the energy dissipation coefficient are increased.The new damping wall has a good energy dissipation capacity,which can well improve the seismic performance of the traditional infilled-frame structure in the earthquake area and has a good research application prospect.更多还原
