摘要
以混凝土强度为主要参数,结合环境和使用条件给出了大气环境下混凝土碳化深度和碳化残量的预测模型。运用可靠度的原理,计算了结构的耐久年限及对应的可靠指标,分析了影响钢筋混凝土结构耐久性的主要因素。
The model for predicting the carbonated depth and carbonated residue content of concrete under the atmospheric environment is established on the basis of the main parameter of the concrete strength. The endurance life and corresponding index of reliability of the reinforced concrete structure are calculated by the theory of reliability. The main factors influencing the durability of the reinforced concrete structure are analyzed.
