Abstract
Strengthening of beams is most popular technique over decade in order to compensate the deficiency of reinforcement, misplacing, or due to unusual practices etc either in tension or in shear point of view. This study mainly focuses on effect of Carbon fiber reinforced laminate stirrups on strengthening of beam in shear criteria. The objective of this study is to find out the increase in load carrying capacity and deflection profiles of shear deficient beams which are strengthen by CFRP laminates in 900 strip orientation and 450 strip orientations for different span to depth ratios 3 and 4. Over all six beams were modeled and analyzed numerically through Abaqus 6.1 version. All six beams categorized into span to depth ratio 3 and 4. Each group having a control beam, and remaining beams strengthened with 90degrees and 45degrees orientation of CFRP stirrups.
