Abstract
The topic of this study is to strengthen cracked beams with prefabricated RCrectangular cross sectional plates. The damaged beams were repaired by epoxy basedglue. The repaired beams were strengthened using prefabricated RC rectangular crosssectional plates. The strengthening plates were bonded to the bottom face of the beamsby anchorage rods and epoxy. The strengthened beams were incrementally loaded up tomaximum load capacities. The experimental results were satisfactory since the loadcarrying capacities of damaged beams were increased approximately 47% due tostrengthening. The post elastic strength enhancement and the displacement ductility ofall the beams are researched during the experiments. The experimental program wassupported by a three dimensional nonlinear finite element analysis. The experimentalresults were compared with the results obtained from the beam modeled with ANSYSfinite element program.
