I am modelling a simply supported reinforced concrete beam with FRP sheets under it the connection between beam and sheet is adhesive agent the problem I am having is that the load is not reaching the FRP sheets.
The connection between the FRP and the beam is epoxy agent modelled using cohesive elements like this video https://www.youtube.com/watch?v=bDJkS0OoM7A
Two option you may do to ensure the interaction between FRP and the substrate, first you can make the FRP fully bonded via tie connection and the second you may use an interface element like cohesion element.
