Abstract

The main objective of this study is to parametrically investigate the effect of pre-and post-corrosion and loading damage on concrete-jacketed reinforced concrete (RC) columns under uni-axial loading. A model capable of evaluating the squash load of un-jacketed or jacketed RC columns with and without corrosion damage was induced. The parametric studies based on this model are meant to investigate the effect of rebar corrosion on the axial compression capacity of jacketed RC column. It was concluded that the longitudinal rebar corrosion has more distinct effect on the peak load than that of web rebar. The jacketing rebar corrosion has more distinct effect on the peak load than that of substrate rebar.
