Notes. (1) The number of a specimen, HSAA-BB, represents high strength steel rebar HRB500 with the targeted amount of corrosion, = 0. AA under strain rate of BBsā1; (2) is the average corrosion degree. is the maximum corrosion degree. and are the corresponding yielding and ultimate loads measured during the tensile tests of the corroded high strength rebars (MPa), respectively.
