化工结构基于强度准则的优化维修决策

THE OPTIMUM DECISION OF CHEMICAL STRUCTURE BASED ON STRENGTH CRITERION

根据化工侵蚀性环境下工作的钢筋混凝土结构的服役特点，研究了结构基于强度维修准则时的加固策略，针对工程实际中常存在的待维修结构要求条件，分别建立了在不同前提情况下的结构维修加固决策的数学模型，并依此设计了在役钢筋混凝土结构基于维修目标可靠度条件下的构件截面维修加固策略。

The paper, according to the serving character of reinforced concrete structures in chemical corroded environment, researches in the reinforcement decision of structures based on the criterion of strength maintenance. Refers to the requirement condition of maintaining structures in practical, the paper also builds the mathematics model of reinforcement decision under different case, and designs the reinforcement decision of the section of reinforced concrete structures based on the maintenance reliability.
