1) equivalent system
等效体系
1.
This paper presents a concept of “equivalent system” on the basis of the analysis for the way of solving problem by displacement method.
在对位移法解题途径分析的基础上,提出了“等效体系”的概念。
2) equivalent SDOF
等效单质点体系
1.
Three general methods of calculating yield point and yielded stiffness of equivalent SDOF are introduced and the yield point and the yielded stiffness of three frame structures are compared using above given methods in this paper.
文中介绍了三种曾经建议的由结构能力曲线确定等效屈服点和屈服后刚度的方法,对三个框架结构算例采用上述建议方法计算的等效屈服力和屈服位移进行了对比分析,并以此屈服点和屈服后刚度作为等效单质点体系的恢复力骨架曲线,采用非线性动力时程分析法计算了等效单质点体系在罕遇地震下的最大弹塑性位移,通过与杆系模型非线性动力分析法计算的顶点位移对比,从而得到关于能力曲线简化方法的建议。
