摘要
利用压剪试验机对所设计的一种双弧形钢阻尼器样品进行了多种工况下的耗能性能试验,通过试验所获得的力—位移滞回曲线可知,该阻尼器通过自身的弹塑性变形能够耗散外界输入的部分能量,具备一定的横向耗能能力且性能较为稳定,从而使被保护结构处于安全的环境中。
In this paper,one kind steel dampers with double arc shape is studied under several displacement amplitude and two deformation rate by compression and shear testing machine. The force-displacement hysteretic curves obtained from experiment show that this damper can dissipate the energy steady in the horizontal direction by elastic-plastic deformation of steel,and keep the protected structure in safe environment.
