| Summary: | Abstract An experimental study is proposed in this paper to investigate about the durability of monorail track beam after acid rain corrosion in a monorail transportation system. Firstly, a 20-m full-scale beam was built to analyze the causes of corrosion of a monorail track beam, and the corrosion pool was used to make a catalyzed corrosion test on the beam. Then the strand steels were contrasted after 3000-h of accelerated corrosion test. Next, experimental study was performed and the characteristics of strand corrosion in the monorail track beam with corrosion is discussed based on experimental observations. The results show that after the acid rain corrosion, the cross-sectional area of the prestressed steel strand was reduced, although the degree of corrosion was not serious compared with the plain bars, it was more dangerous because of high stress, so further research is necessary to clarify the effects of acid rain corrosion on the durability of the track beam. |
