520			_alarge number of existing concrete bridges in distressed condition in India and other countries, and they need retrofitting solutions. External post-tensioning is a prime technique for bridge retrofitting. It is being applied for retrofitting of bridges in India and other countries. Although the technique is becoming popular in retrofitting, various issues regarding performance of post-retrofitting behaviour need to be studied in detail. RC beam specimens of rectangular section were distressed by means of cracks to a certain limit, and were retrofitted by external post-tensioning. Retrofitted specimens were tested to fail to study the post-retrofitting behaviour. Retrofitting has increased the ultimate load carrying capacity by 81% with reference to the control beam, and recovered the deflection. This paper intends to report the results of the experimental investigations, and conclusions.
