The components of force transfer developed by fiber reinforced plastic (FRP) grids are investigated under uniaxial tension and compression loads and under a bending load. Three contributing mechanisms of force transfer in FRP grids are studied: chemical adhesion between the concrete and resin, bonding along the two rough sides of the longitudinal member, and bearing against one side of the transverse members. Development length necessary for force transfer is investigated in three splice details.
