RCC skew bridges are more often encountered in the highways. Recent growth of transportation infrastructure has increased the number of skew bridges in India. In this paper the RCC skew bridge with skew angle 600 is taken into consideration and its analysis is done using the finite analysis software. The bridge is subjected to dead loads, IRC standard moving loads and also response spectrum analysis is done to take into account the earthquake effects. The behavior skew bridge is observed in terms of bending moments, shear force and torsional moments and then the design of pier is done. The RCC bridges undergo the deterioration over the period of time and there after it may not be able to withstand the given stress. Deterioration causes loss of strength and alternatively in moment of inertia of RCC members. This effect can be taken into account by effective moment of inertia concept specified in various codes. It is necessary to retrofit the piers. The paper implements Indian code IS 15988-2003 to retrofit the RCC bridge pier taken into account for this study. After jacketing the pier shows satisfactory results for the given loads. In this paper two span RCC T girder skew bridge is analysed for its forces. Pier are considered as a subject of study and its modelling as degraded structure and check for safety for current critical load combination is taken. Form the results it is found that pier needs retrofitting so it is done with the method of RCC jacketing and again it is checked for structural strength criteria and serviceability criteria. RCC jacket have improved its flexural capacity, shear capacity and also made bridge safe in strength and serviceability.
