Analysis of factors affecting effective bond length of fiber reinforced polymer composite laminate externally bonded to concrete substrate
MetadataShow full item record
Bond length is one of factors which are important with regards to the effective technique of improving the shear capacity of a concrete member by externally bonding fiber reinforcement polymer laminates. A number of models have been proposed by various researchers over the years but there is not a single model that can definitely predict the effective bond length (effective bond length). The models proposed show a disparity between the analytical and experimental values. This study takes a holistic approach to rationalize all the influencing factors. FEA is done of the existing experimental test results by calibrating for measured failure load and effective bond length values. A sensitivity study is undertaken to understand the influence of the affecting parameters on shear stress and effective bond length.
