| Corrosion of steel is the predominant deterioration mechanism of reinforced concrete structures throughout the world. This thesis presents the work performed on VecTor2, a nonlinear finite element analysis program developed at the University of Toronto, for analysis of corrosion damaged reinforced concrete structures. Two well-known types of corrosion, namely uniform and pitting, were considered for modelling. Corrosion damage was incorporated in the algorithms of VecTor2 through reduction of the sectional area of reinforcing steel, the bond strength between the reinforcement and concrete, and the mechanical properties such as yield strength of a corroded reinforcing bar.;The employed techniques for incorporating corrosion damage in VecTor2 successfully reproduced the load-deflection response of published experiments. Stochastic simulation of the same experiments, performed by employing the stochastic tools of VecTor2, demonstrated the sensitivity of response quantities to changes in various input parameters forming the basis for further research. |
