Strengthening Of Prestressed Steel–concrete Composite Beams Using Carbon Fiber

Strengthening of structures using external post-tension Carbon fiber reinforced polymer systems have proven to be an efficient method as such system increases the structural capacity and reduces cracks and deflection . A finite element model three-dimensional is set up to study the impact of composite beams strengthened using externally post-tensioned Carbon fiber reinforced polymer system under flexural behavior using parameters like deflection, maximum load carrying capacity , tendon forces and cracks are considered under static loading . A test program approves the design approach and gives some serviceability information. Consequences of the parametric study will give reasonable guidelines for the designers in choosing the proper reinforcement ratio and degree of prestressing for required design stress and serviceability of the bridge girders. End from the test program and design suggestions are give .
