一种耗能牛腿的力学性能试验研究

EXPERIMENTAL STUDY ON ENERGY DISSIPATION BRACKET

  • 摘要: 提出了一种耗能牛腿的新型构造方式,具有构造简单,易于更换的特点,并对其进行了低周反复试验。试验选用多种不同宽厚比的耗能板,研究了耗能牛腿的力学性能和疲劳性能,分析了耗能板的宽厚比对耗能牛腿力学性能的影响。实验结果表明:新型耗能牛腿具有良好的滞回性能和稳定的耗能性能;在一定范围内,耗能板的宽厚比越大,耗能牛腿的延性和耗能能力越好。

     

    Abstract: A new Energy dissipation bracket is proposed, which is simple in construction and easy to be replaced. Quasi-static tests were conducted. The mechanical and fatigue properties of the bracket with different ratios of width and thickness were studied, and the influence of the width-thickness ratio of the energy dissipation plate on the mechanical properties of the bracket was analyzed. The test shows that the energy dissipation bracket has good hysteretic property and stable energy dissipation property. In a certain range, the larger the width-thickness ratio of the energy dissipation plate, the better the ductility and energy dissipation capacity of the energy dissipation bracket.
