【摘要】 众多的影响因素，使钢筋混凝土单一构件的可靠度评价仍停留在特定条件下的定性认识阶段，探求简单、合理的定量分析方法很有必要．针对锈蚀钢筋混凝土构件可靠度影响因素的不确定性，在专家经验的基础上，应用模糊数学方法，建立了锈蚀钢筋混凝土构件可靠度模糊评价的因素集和权重集，提出了一种可靠度模糊评价的分析方法，进一步对锈蚀钢筋砼构件可靠度进行了评价，并通过实例验证了该方法的可行性．更多还原

【Abstract】 Reliability evaluation of reinforced concrete under given conditions is still at the qualitative stage because of many influencing factors. It is necessary to seek an appropriate quantitative method for reliability analysis now. Aiming at the inaccuracy of factors influencing the reliability of rusted reinforced concrete element, the authors applied the fuzzy mathematics to establish the factor set and weight coefficient set for the reliability of rusted RC element on the basis of expert experience. An analysis method for fuzzy evaluation of reliability is put forward. Furthermore, reliability of rusted RC element is evaluated and verified by testing results.更多还原
