摘要
提出了工程结构抗震设防标准的决策方法，该决策方法以结构初始造价分析和地震损失分析为基础。建立了结构初始造价与设计烈度的关系，并提出了地震损失的估计方法。使用该决策方法导出了最佳设计烈度和重现周期的解析表达式，从而得出了对抗震设计具有重要意义的结论。
The decision-making method of earthquake-resistant fortification standards of engineering structures, which is based on the initial cost analysis and the earthquake loss analysis of structures, is presented. The relation between the structural initial cost and the design intensity is established, and the method of estimating the earthquake loss is presented. The analytical expressions of the optimal design intensity and return period are deduced by using the decision-making method, and therefore the conclusions of great significance to earthquakeresistant design are drawn.
