Abstract

Abstract

In order to evaluate the impact of environmental effects on the shearing reliability of reinforced concrete (RC) beams strengthened with side near surface mounted (SNSM) carbon fiber-reinforced polymer (CFRP), the time-varying function model of the shear bearing capacity of the strengthened beams considering environmental impacts was established. Then, based on the JC method, the time-varying shear reliability of RC beams with different ratios of standard values of dead load and live load before and after reinforcement was calculated, and then the service life of the strengthened one was evaluated. The results showed that the shear reliability of RC beams decreased slowly with the increase of service time in the early stage, and decreased rapidly and linearly in the later stage. Compared with unstrengthened beams, the reliability of strengthened beams had been improved to a certain extent. When the RC beams were serviced 80% of the base period, its shear reliability could continue to be serviced about 8% of the base period after strengthened with SNSM CFRP technique.
