Summary: | 碩士 === 國立臺灣科技大學 === 營建工程系 === 102 === Reinforced concrete (RC) structures or buildings deteriorate over time when exposed to corrosive environments. When the service-life in terms of the structural safety or serviceability of a deteriorating RC building does not meet the original target, lifecycle maintenance strategies should be implemented. Once the cause of corrosion has been identified, structural members, beams, or columns with reinforcing steel components corroded by carbonation or chloride ingress can be repaired or retrofitted. Therefore, there is an need for a method that can be used to assess the durability of an RC building and then determine an appropriate maintenance strategy to prolong its service life.The main purpose is to build an assessment method of the durability for an RC building. Besides of the preliminary assessment including the visible investigation, the detailed assessment of the durability consists of several tests of material properties. Engineers can follow the proposed assessment method to determine the durability of an RC building. Futhermore, according to the quantitative index of the durability and deterioration factors obtained from the detailed assessment, the appropriate maintence strategy can be suggested to prolong the service life.
