Because of antimagnetic requirements of magnetic nails for the heavy load way running AGV in the automated container port,fiber reinforced polymer bars are used as dowel bars in the concrete layer for its excellent antimagnetic properties.However,there is no specific design method on the FRP bars used in road currently.By reference on traditional steel dowel bar computing theory and 3D finite element numerical analysis method,with on-site load transfer coefficient experimental results,the applicability of the relevant design methods are verified and meanwhile some suggestions for optimization design are proposed.
