Numerical analysis for effect of sustained load on bond behavior of concrete structure strengthened with near surface mounted FRP

In this paper, a pull-out concrete block strengthened by near surface mounted (NSM) FRP plate corresponding to different bond stress - displacement relationships is used to study the effect of sustained load on this strengthening system. Concrete - resin - NSM FRP plate bond performance is investigated in full characteristics of bond such as linear, bilinear, unilinear behaviors by numerical analysis.
