| Research Abstract |
Beam specimens, which are damaged by ASR, corrosion and combined deterioration due to ASR and corrosion, are tested. From these results, flexural capacity of beam specimens, which have combined deterioration, is evaluated. Bond strength specimens, which are same section to beam specimens, are tested. Bond strength between reinforcing steel bar and concrete are evaluated. In the case of beam specimens affected deterioration of bond strength, calculation values used FEM Analysis are evaluated.
