摘要
目前钢筋混凝土结构可靠度研究大多数没有考虑钢筋锈蚀的影响。从考虑钢筋面积的降低,建立锈蚀钢筋混凝土结构抗力的模型,应用结构可靠性分析的简化方法计算结构的可靠度来评估混凝土结构可靠度。通过分析,还可以进行目标可靠度下的寿命预测。
At present, the influence of rust reinforced bar has not be considered in the majority of studies of the reliability of reinforced concrete structure. This paper studies the reliability evaluation of concrete structure in considering of decreasing area of reinforced bar, establishing resistibility model of rust reinforced concrete structure and calculating structure reliability by means of applying short - cut method of structure reliability analysis. The service life forecast can be carried out under the degree of reliability of aim via analysis.
