Abstract

In this study, in order to propose the effective rupture control method of Aramid FRP (AFRP) sheet for flexural strengthening of RC beam, falling-weight impact loading tests for the strengthened RC beams were conducted. In these experiments, the followings were investigated; 1) effect of the unit mass of the flexural strengthening AFRP sheet; 2) effect of the horizontally bonded AFRP sheet to the side surface of the beam; and 3) effect of the U-shaped bonding AFRP sheet. The results obtained from these experiments were as follows: 1) rupture of the flexurally reinforcing AFRP sheet can be effectively controlled by increasing the sheet volume; 2) effect of the horizontally bonded sheet was not much; and 3) shear cracks can be restrained by the U-shaped bonding sheet, however rupture of the sheet for flexural reinforcing cannot be restrained.
