数值分析 显示算法 非线弹性 滞回曲线-Numerical analysis showed that the algorithm the linear elastic hysteresis curve

最新版本的地震反应谱分析软件 Nspectra，可以考虑单自由度体系的刚度退换，滞回曲线的捏缩、滑移等特性

滞回曲线分析 计算能量耗散系数 滞回曲线的加载圈数(Press the Analyze button, and the hysteretic loop will be decomposed into separate loops, from which the hysteresis loop area, secant stiffness, equivalent viscous damping coefficient are obtained.)
