Abstract

Abstract

The variations of the temperature, humidity, salt frog and acid rain in Shenzhen area and their effects on durability of concrete structures were described. According to the survey and field test data of building durability in Shenzhen in the past 20 years, the classification weighted assessment method was adopted to evaluate the effect factors of durability. Then the durability damage grade of concrete structures was evaluated and the durability status of concrete structures in Shenzhen was obtained. The factors affecting durability of concrete structures in Shenzhen area, including corrosion rates of reinforcement bars, concentrations of Cl^-, relative carbonation depths of concrete, area damage ratios, strength grades and crack widths, were fuzzily evaluated by the analytic hierarchy process, and the key factors were got.
- environment condition,
- classification weighted assessment method,
- key factor,
- analytic hierarchy process
