摘要
本文基于大地震发生的半马尔可夫过程模型，建立了服役结构抗震维修动态规划决策模型。文中考虑了钢筋锈蚀对结构抗力的影响，利用“分枝限界法”计算结构系统可靠度，并进行安全性等级划分，在此离散状态及离散时间的基础上，运用技术经济评价法，建立了动态规划决策模型。
Using a semiMarkov process model to characterize the recurrence of violent earthquakes, a model of dynamic programming of repairing strategies for existing structures is proposed. The effect of the steel rusting on the structural resistance is also considered. The 'BranchandBound Method' and safety classification method of structures are used to analyze the reliability of the structure system. The practicability of the model is tested by a simple frame structure.
