剪切金属软钢阻尼器设计与试验研究

Design and experimental study of metal shear hysteretic damper

伴随着地区抗震等级的提高,在建建筑不得不进行加固,剪切金属软钢阻尼器的初始刚度大、耗能好和体积小的特点,可对在建建筑进行加固。分析剪切金属软阻尼器的构造形式及工作机理,加工了2组不同截面尺寸,每组3个试件的剪切金属软钢阻尼器,进行水平滞回试验,研究其水平滞回性能、疲劳性能和耗能性能。研究表明,剪切金属软钢阻尼器具有稳定的水平滞回性能、良好的疲劳性能和较好的耗能性能。

With the increasing level of earthquake,the building had to be strengthened,the initial shear stiffness of the metal damper,energy dissipation and the characteristics of small size,can be in the construction of the building reinforcement. Analysis of the structure and working machine shearing soft metal damper,two groups of different section size of the processing. Shear metal mild steel damper three test pieces in each group,the level of the level of hysteretic test,hysteretic behavior,fatigue resistance and energy dissipation. The results show that the shear hysteretic damper with metal level hysteresis stable performance,good fatigue performance and good energy performance.
