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。
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.
该指标体系设立目标层、准则层、领域层和指标层4个层次的指标，共有46个指标。
This system includes 46 indexes in 4 layers: goal layer, criterion layer, field layer, and index layer.
指标层由准则层下的各项指标因子组成，分为定性和定量两种类型。
The Index layer is formed by a number of indicators, divided into qualitative and quantitative.
