Bond-slip response of FRP sheets or plates bonded to reinforced concrete beam under dynamic loading

Abstract

The performance of bond-slip of fiber reinforced polymer (FRP) sheets or plates bonded to reinforced concrete (RC) beam under dynamic loading are studied. Model for composite beam are developed and simulations are carried out by developing finiteelement (FE) models in ANSYS under static and dynamic loading. Parametric studied arecarried out by varying width of the FRP sheets or plates, their thickness, and for compressive strength of concrete. The RC beam subjected to static load is designed according to the ACI 318-11 and ACI 440R-08. Further, the beams are subjected to dynamicloading by applying harmonic excitation. The performance of the composite beam is analyzed in terms of load-slip relationship. The theoretical results are compared withtheresults reported in the standard literature from experiments conducted.
