Shear Strengthening Effects of RC Beams Using Aramid Plate Strip

Abstract:

For the strengthening material mainly used at construction sites, steel plate and fiber can be counted in general, and for the fiber case, a composite material like glass fiber, carbon fiber and aramid fiber for reinforcing is commonly used in concrete structures. For the end development method, only the development effect has been verified through experiments without providing an effective development design per FRP strengthening quantity on a tensile surface. This study acknowledges the strengthening effect through behaviors of each specimen and test results by performing tests on total 4 reinforced concrete beams with the strengthening quantity and its position as variables in order to evaluate the performance of the Peel-ply method using aramid fiber plate to increase bonding strength with the basic material concrete.
