摘要
本文提出了“耗能器应具有多道耗能减震防线”的思想， 研究设计了加劲圆环耗能器， 并对其进行了循环加荷试验， 考察了耗能器的工作性能和耗能性能， 给出了耗能器的恢复力模型。研究结果表明， 加劲圆环耗能器是一种工作性能稳定、耗能能力强、具有两级耗能减震防线、构造简单。
A new energy dissipator design idea of “energy dissipator must have many lines of energy dissipating” is presented According to the idea, a new added stiffness circular ring energy dissipator(ASCRED) is designed The property experiment of ASCRED under cyclic reversed loading is conducted The working behavior and energy dissipating behavior are investigated and the restoring model of ASCRED is set up The experimental results show that ASCRED can dissipatea great deal of energy and is an effective energy dissipator with two lines of energy dissipating It is easy to design and make, with high initial stiffness and yielding force, and stable in working behavior and hysteretic behavior Its application prospect appears to be highly promising
