Abstract

Prestressed concrete bridges require strengthening due to aging, frequent over load, deterioration, etc. Carbon fiber reinforced polymer (CFRP) composites have been successfully used for enhancing flexural, shear, and axial strength of RC and PC members. Increase in traffic service load on highway bridges dictates replacement of the bridge super structure or adoption of a structural upgrade system. Strengthening of existing concrete bridges with conventional construction materials results in an increase in the dead load, and possible decrease in bridge clearance. The use of CFRP composites is considered a practical alternative for flexural strengthening of prestressed concrete bridge girders. The effectiveness of the use of CFRP depends on several factors, which are not yet quantified. This paper presents a finite element investigation on the effectiveness of CFRP composites in flexural strengthening on AASHTO type II prestressed girder.
