چکیده
|
The chloride corrosion of reinforcing steel in reinforced concrete (rc) structures is a significant reason for premature deterioration and failure of rc structures in aggressive environments such as the persian gulf region. this is one of the major sources of engineering and economic problems in developed countries. on that account, modeling chloride permeation and investigating different methods for the repair and maintenance of rc structures exposed to corrosive environments are considered to be essential for optimizing the service life and life cycle cost of these structures. in this research, a finite element model is applied to assess the timedependent capacity of corroded rc structures applying nonlinear analysis; this includes the impact of corrosion on inelastic buckling and lowcycle fatigue degradation of reinforcements. in this analysis, the influence of shotcrete repair after the initial cracking of concrete cover as a rehabilitation method on the performance of a corroded square rc column due to chlorideinduced corrosion is investigated.
