Abstract:
Based on the tests conducted to investigate the flexural behavior of strengthened reinforced concrete(RC)T-beams with stainless steel wire mesh and permeability polymer mortar which took the reconstruction project of a bridge in Cangzhou, Hebei Province as the project background, the finite element program was used to analyze the flexural performance of strengthened T-beams. The influences of concrete strength, longitudinal reinforcement ratio, amount of stainless steel wire and secondary loads on the flexural performance were discussed. The analytical results show that with the increase of the concrete strength, longitudinal reinforcement ratio and amount of high strength stainless steel wire, yield capacity, ultimate capacity and yield deflection are improved, but the ultimate deflection decreases and the ductility of members wanes. The performance of the strengthened members under secondary load is bounded by which can yield under first load or not. If it could not yield before strengthening, the influence of the magnitude of the first load on the performance of the strengthened members is negligible, otherwise, the performance of the strengthened members is promoted greatly with the increase of the magnitude of the first load. The final failure modes of the strengthened members are affected by the longitudinal reinforcement ratio, the amount of stainless steel wire, concrete strength and so on.
