WebAug 17, 2010 · The experimental program was conducted on five RC columns with inadequate tie spacing, 90-degree hooks at tie ends, and plain (undeformed) reinforcing bars. Columns were tested under a constant axial load of 27% of axial capacity and under reversed lateral cyclic loading. WebJul 1, 2006 · Deterioration of existing concrete structures can be due to corrosion of reinforcement, carbonation, freeze and thaw, etc. Numerous concrete structures constructed in the past in countries like USA and Japan do not meet current seismic design codes especially concerning shear capacity and ductility.
