Axial–Flexural Interaction in FRP-Wrapped RC Columns

Behaviour of FRP wrapped circular concrete columns under eccentric loading

Theoretical model for slender FRP-confined circular RC columns

An important application of fiber-reinforced polymer (FRP) composites is to provide confinement to reinforced concrete (RC) columns to enhance their loadcarrying capacity. However, this application is generally restricted to short columns as existing design guidelines do not contain provisions for the design of FRP jackets for slender columns. This situation has been due to both the scarcity of...

Confinement Characteristics of Rectangular FRP-Jacketed RC Columns

In this study, FRP jackets were investigated for their confinement effectiveness on rectangular RC columns. Thirteen reduced-scale short columns were tested to failure in axial compression. Variables investigated include: the type of fibers (AFRP, CFRP or GFRP), the thickness of the jacket, the aspect ratio of the rectangular cross section and the radii of the corners. For square columns, GFRP ...

intermediate layer effects in performance of frp-confined rc columns

the use of polymer composite (frp) as a reinforcement material for the repair and strengthening of important components of reinforced concrete structures, particularly columns, has found wide spread. in this study, the effect of intermediate layer on improving the confinement behavior of reinforced concrete columns has been investigated. to achieve the objectives of the study, 14 cylindrical re...

Axial Compressive Strength of Reinforced Concrete Columns Wrapped with Fiber Reinforced Polymers (FRP)

This paper presents the results of a study on the axial compressive strength of columnsstrengthened with FRP wrap. The experimental part of the study included testing 6 reinforcedconcrete columns in two series. The first series comprised three similar circular reinforced concretecolumns strengthened with FRP wrap. The second series consisted of three similar square columns,two with sharp corner...
