多因素影响下的混凝土结构耐久寿命预测方法

Life Prediction Method for Durability of Reinforced Concrete Structures under multifactor influences

将影响混凝土结构耐久性的因素分为程度型指标和速度型指标,在对构件外观状况、裂缝宽度、钢筋锈蚀和承载力衰减进行耐久性评判的基础上,计算结构的耐久性劣化程度和劣化速度,提出一种混凝土结构耐久寿命预测方法.经实例计算表明,该方法计算过程简单,具有一定的工程推广意义.

The factors influencing concrete structures durability are divided into degree index and speed indicator.Based on the durability assessment of components＇ appearance condition, crack width, steel corrosion and bearing capacity attenuation, this paper proposes a life prediction method for durability of concrete structure and calculates the structure durability degradation and deterioration speed. The test results show that the method is very simple and it can be applied to practical engineering program.
