Abstract
Through accelerated method using external current and 5% Nacl solution, different corrosion results of rebars in columns were attained to study damage patterns of columns under large eccentric loading. Results indicated that columns with different corrosion degree due to different corrosion time developed defferent damage modes. Firstly, results show typically large eccentric damage for columns with different corrosion degree. Secondly, with the increase of corrosion degree, different damage patterns appear under lower loading including reduction of compressive damage scope, expansion of crack zone and earlier crack. These results can be considered as reference to guarantee safety of structures with eccentric loading under corrosion environment.
