ANALYSIS OF RC STRUCTURES CONSIDERING REBARS CORROSION

One of the most detrimental processes which adversely affects the life of a reinforced concrete structure is the corrosion of the reinforcement. This concerning process whose long-term indications are revealed in the forms of durability and serviceability degradation, weakens the structural performance widely, specially in the structures which are exposed to a chloride bearing environment.The major aim of this research is to investigate the effects of corrosion as one of the most important causes of degradation on the seismic response of RC frames. Here numerical studying has been conducted using a finite element program named COM3. The results were verified using experimental data obtained previously. Cracking, loss of cross sectional area and change in bond strength are some items which have been taken into account. For evaluating the seismic performance of the structures, incremental dynamic analysis is done.
