| Abstract: | Based on the Bond-slip between the steel bars and concrete,the FE models of RC simply supported beam in different corrosion ratios were built by ANSYS software for analyzing the load bearing capacity of corroded RC simply supported beam.The elements of SOLID 65,LINK 8 and Combine 39 were used to simulate concrete,steel bar and bond-slip between bars and concrete respectively.The effect of corrosion ratio on bonding force between bars and concrete was simulated by adjusting the parameter of Combine 39.Beside... |
