| 摘 要： | 在假定双线性系统和弹性系统瞬时输入能量相等的基础上，得出了地震作用下双线性系统最大位移与弹性系统最大位移的关系，并推出双线性系统最大位移上，下界限的简化公式，时程分析结果表明，双线性系统最大位移大多数落在此上下限范围内。研究结果时对双线性隔震结构的抗震设计有一定参考价值。

| Abstract: | Based on the assumption that the instantaneous input energy is equal for elastic and bilinear SDOF systems, the relationship between the maximum displacement of a bilinear system and that of a elastic system is obtained. The simplified upper and lower bounds of the maximum displacement of the bilinear system are suggested. The results of time history analysis show that the maximum displacements of the bilinear systems of different periods mostly fall between the proposed upper and lower bounds. The results can be referenced by seismic design of structures |
