Abstract:
This paper is based on an experimental analysis carried out in order to identify the best method
of installation of CFRP strips to enhance the flexural capacity of a reinforced concrete beam. Of the two
methods of installation; EBR (externally bonded reinforcement) and NSM (Near surface mounted) the NSM
method has been proven to be better in qualitative terms. The research gap of quantitative validation of this
concept is fulfilled by this research paper. Two new methods of integration of EBR and NSM method were
also experimented with the objective of increasing the flexural capacity of reinforced concrete elements by
increasing the effective area of CFRP strips used. Suggestions to eliminate the failure modes observed in the
experiment and to enhance the flexural capacity are also discussed in this paper.
