| Abstract | Corrosion of reinforcement is one of the major causes of degradation of performance of
concrete structures in a severe environmental condition mainly due to neutralization of
concrete or chloride attack. Particularly in earthquake prone region, it becomes necessary to
evaluate the performance of these deteriorated structures under seismic action to ensure the
safety of the structure. Therefore, to examine the dynamic behavior of reinforced concrete
structures such as strength, stiffuess, ductility and energy absorption under both severe
corrosive and seismic condition, an experimental study was carried out on sixteen reinforced
concrete piers. All the specimens were having exactly same size though, axial load, design
method and corrosion condition were different. The specimens were tested with identical
loading cycles. The results show that the performances were seriously affected by corrosion of
reinforcement and degradation rate was found to be merely depending on degree of corrosion
Especially, rate of degradation of ductility and energy absorption with corrosion loss was
much larger than the reduction of strength. Based on this experimental result, experimental
equations were developed to explain the deterioration degree of strength, ductility and energy
absorption of the pier with corrosion loss of reinforcement. |
