| 摘 要： | 基于最大变形和累积耗能线性组合的双重破坏准则及破坏指标，对单自由度结构进行了倒塌分析．并将Ｑ模型法引入框架的倒塌分析，通过与模型试验结果对比表明，用等效单自由度体系代替多自由度体系进行能量时程分析是简便可行的．

| Abstract: | Based on the double control damage criterion and index of the linear function of the maximum deformation and cumulative hysteretic energy, the collapse of the SDOF structures is analysed. And the Q model is used for analysis of the collapse mechanism of R.C frame structures and the comparison of the results of the calculation with the model experiment shows that it is simple and practicable for the equivalent SDOF system to stand for a MDOF system in the step by step numerical energy analysis. |
