Numerical Studies on Strengthening of Continuous Steel-Concrete Composite Girders Using CFRP
Steel-concrete composite girders are widely used in the construction of bridges and buildings. However when they are provided in continuous spans, a loss of strength and composite action will be occurring at the hogging moment region due to the development of tension in concrete and compression in steel. Limited works have been done to study this shortcoming in these widely used girders. Carbon fiber reinforced polymer (CFRP), is found to have lot of untapped potential for improving the strength of girders. This paper presents an analytical investigation into the behavior of composite girders strengthened in hogging moment region using CFRP. Effect of different arrangements and thickness of CFRP laminates are also being compared for different geometries. CFRP was found effectively improve the strength of composite girders in the negative moment regions especially when used in the form of strips.
