Strengthening of RC beams by UHPFRC jacketing using different configurations. Jacketing using precast panels attached by epoxy or fresh cast in a mold. Three sided jacketing resulted in high capacity enhancement but reduced ductility. Two-sided and bottom jacketing yielded strength enhancement with high ductility. FE modeling of jacketed beams captured the experimental response reasonably well.
