Existing deteriorated reinforced concrete (RC) structures need strengthening to extend service life. Fibre polymer (FRP) has been widely used strengthen sound structures, but its application on damaged still needs be investigated. This paper presents non-linear finite element analyses conducted assess the flexural behaviour of corrosion-damaged RC beams strengthened with externally bonded FRP. ...

The strengthening and repair of existing structures using bonded carbon fiber reinforced polymer, CFRP, laminates has attracted a great deal of attention in the past two decades. Investigations clearly indicate the great potential of this method for restoring the capacity of corroded steel beams and improving their fatigue life. One important issue regarding the use of this technique in strengt...

The use of externally bonded fiber-reinforced polymer (EB-FRP) composites for shear strengthening reinforced concrete (RC) beams presents many challenges given the complex phenomena that come into play. Premature bond failure, behavior interface layer between FRP and substrate, brittle nature cracks, adverse interaction internal steel stirrups EB-FRP are some these phenomena. Compared to experi...

Many opportunities are becoming available for using composite materials to strengthen/upgrade existing reinforced concrete (RC) structures. This paper focuses on a new technique for the seismic upgrade of RC beam-column connections in gravity load-designed (GLD) frames by the application (combined or not) of FRP rods and laminates. The FRP rods provide flexural strengthening, whereas the lay-up...
