Paper Title:
Experimental Study of Flexural Capacity on RC Beams Strengthened with the FRP-Bolt Strengthening Technology
  Abstract

On the basis of the destructive characteristics of aging RC beam bridges, experiments are conducted to examine and compare the effect on RC beams strengthened with FRP surface adhesion (EB-FRP) and FRP-bolt hybrid boding (HB-FRP). In particular, the influence of pre-cracking level on RC beams strengthened with the hybrid bonding of FRP is assessed. The experiment results show that the hybrid bonding of FRP is a more reliable strengthening technique which can improve the Flexural capacity of beams. The new bolt-fastening technique does not rely on bearing to transmit the interfacial shear, but increases the interfacial bond by resisting the separation of the FRP laminate from the concrete substrate by the bolt pretension instead. This study contributes to direct the design and the construction of HB-FRP.
