Moment redistribution in continuous plated RC flexural members. Part 2: Flexural rigidity approach

Adhesive bonding plates to the surfaces of reinforced concrete members is now frequently used to increase both the strength and stiffness. However, because of the brittle nature of the plate debonding mechanisms, plating is often assumed to reduce the ductility to such an extent that guidelines often preclude moment redistribution. Tests on seven full-scale flexural members have shown that significant amounts of moment can be redistributed from steel and carbon fibre reinforced polymer (FRP) plated regions. In this paper, a procedure is developed for quantifying the amount of moment redistribution that can occur in externally bonded steel or FRP plated members which can be used to design plated members for ductility.D.
