摘要
以大气环境下钢筋混凝土老化为主要因素,分析了钢筋混凝土梁老化期的可靠性,指出了钢筋锈蚀的前提条件是混凝土碳化,研究了混凝土保护层厚度和混凝土强度等级对钢筋混凝土结构承载力的影响,进而分析对其梁的可靠度影响。
The ageing of reinforced concrete in atmospheric environment is as the main element,analysis on the reliability of reinforced concrete in period of ageing,the condition premise of corrosion of reinforcing steel is carbonation of concrete,study on the bearing capacity of reinforced concrete structures about concrete cover and strongly affected by concrete strength,then analysis on the reliability influence of its beam.
