| 摘 要： | 推导了钢筋砼结构可靠性优化设计所需的约束条件和目标函数，并建议通过求主要破坏机构来计算结构系统的可靠度，在采用分部优化策略的基础上，实现了结构系统可靠性分析与结构优化设计的有机结合，并将该方法和确定变量的现行设计方法进行了比较，指出了钢筋砼框架结构的系统可靠性优化设计的优点，为工程设计和修订规范提供了理论依据。

| Abstract: | The constraints and the objective functions required in the reliability -based opti-mum design of R. C. frame structure are derived and it is suggested that the reliability ofstructural system may be calculated by mean of seeking main broken mechanism .On the ba-sis of part optimizatioin,the analysis of structural system reliability and structural optimumdesign are combined organically.The advantages of the optimum design of R. C. frame struc-ture based on structural system reliability is pointed out after comparing the method present-ed with exsisting method for establishing the design variables.Optimum design method pre-sented provides an important theoretical basis for guiding he engineering design and modify-ing the standard |
