摘要

本文利用钢塑性滞回变形耗能的特性,提出了两种弧形钢耗能阻尼器,通过分析得出该阻尼器的设计公式,并建立了相应的力学模型。为验证两种弧形钢阻尼器的力学特性,进行了数值仿真和试验测试,并对比分析两种方法得到的结果。结果表明:弧形钢阻尼器具有较高的阻尼比和稳定的滞回特性,可以作为减震结构在桥梁、建筑领域推广应用。
In this paper,two types of arc-shaped steel dampers have been researched.Based on the steel's dissipating energy in hysteresis of plastics,the design formula of the arc-shaped steel dampers and damping force hysteresis loop model are derived.To verify the mechanical characteristics of two types of arc-shaped steel dampers,the FEA simulations and product tests have been done,and the comparative analysis of the results obtained in two ways is made.The results show that the arc-shaped steel dampers have higher damping ratio and reliable hysteretic behavior,so they can be used for bridges and building structures.
