  • Investigation of Critical Diagonal Crack debonding in plated RC beams
    Composites Part B: Engineering, 2008
    Co-Authors: S.k. Sharma, M.s. Mohamed Ali, D. Goldar, P.k. Sikdar
    Abstract:

    Abstract Retrofitting of RC structures by adhesive bonding plates to their surfaces has been found through application, and experience in industry to be highly effective, inexpensive, unobstructive and efficient form of strengthening, stiffening and upgrading the structures. The paper presents fourteen (14) test results on reinforced concrete (RC) beams bonded with tension face plates, inclined plates and side plates to determine the Critical Diagonal Crack (CDC) debonding strength using different types of plates, i.e., carbon FRP, glass FRP and steel plate in the presence or otherwise absence of the internal shear stirrups. The elastic modulus and ultimate tensile strength of the plates of different materials vary between 28–300 GPa and 300–2800 MPa, respectively. Tests show that the Critical Diagonal Crack debonding may not occur at the formation of the Critical Diagonal Crack in the beams that are provided with large amount of longitudinal reinforcement and transverse reinforcement, as it does with beams with less reinforcement. The analytical procedures adopted in this study are capable of predicting the CDC debonding strength of the plated beams with very good accuracy, and are validated with large number of test results taken from the published literature.

  • tests investigating the punching shear of a column slab connection strengthened with non prestressed or prestressed frp plates
    Construction and Building Materials, 2013
    Co-Authors: A Abdullah, Colin Bailey
    Abstract:

    Abstract This paper investigates the effectiveness of bonding non-prestressed and prestressed carbon fibre reinforced polymer (CFRP) plates to the tension surface of concrete column-slab connections in both the serviceability and ultimate limit state. For the prestressed plates different prestressing forces were applied to the CFRP as part of the strengthening technique. The structural response of the strengthened specimens was compared with a non-strengthened reference specimen in terms of punching shear strength, deflection profile, strain, Crack opening displacement and failure modes. It was found that using prestressed CFRP plates improved the serviceability; in terms of deflection and Cracking, but did not enhance the ultimate behaviour as much as the non-prestressed CFRP plates. The development of the Critical Diagonal Crack (CDC) was the main reason for the reduction in the ultimate capacity of the strengthened slabs.
