新型耗能器耗能特性分析

Characteristics analysis of new energy dissipation

提出了一种具有对称结构的新型钢管耗能器,为验证其耗能特性对试件进行了低周往复试验,借助ANSYS有限元软件进一步分析了各构造参数的变化对其耗能特性的影响。结果表明:耗能器滞回曲线饱满,耗能性能良好,各构造参数中对其耗能特性有显著影响的是弧形钢棒,且弧形钢棒的直径和弯曲度取分别为14 mm、10%左右时耗能特性显著提升。

This paper presents a new type of steel damper with symmetrical structure,in order to verify the energy dissipation characteristics of low cyclic\|loading\|test of specimens,by using ANSYS finite element software to further analyze the influence of structure parameters on the consumption characteristics.The results showed that the damper hysteretic curve was full,it has good energy dissipation capacity,the arc steel bar has significant influence on its characteristics.When the diameter and the curvature of the arc steel bar were 14mm and 10%,the energy dissipation characteristics of the damper were significantly improved.
