Abstract |
In this paper, a stress transfer mechanism between near surface-mounted (NSM) fiber reinforced polymer (FRP) plate and concrete was investigated and a reliable analytical procedure for it was presented by using bi-linear bond-slip model simulating the bond behavior of NSM FRP plate. As a result, critical values in the bi-linear model such as maximum shear strength, slip at that time and failure slip at the initiation of softening de-bonding were suggested for being used in the differential equation considering the interfacial characteristic between NSM FRP and concrete. Also, it was found that the bond-slip behavior could be suitably predicted by using the proposed procedure even in the case of various bond lengths from the comparison with bond test result.
