Numerical modeling of circular, square and rectangular concrete columns wrapped with FRP under concentric and eccentric load

Behaviour of FRP wrapped circular concrete columns under eccentric loading

Behaviour of FRP strengthened concrete columns under eccentric compression loading

This paper presents results of testing eccentrically loaded columns externally wrapped with two types of materials. Six cylindrical (205 mm diameter and 925 mm height) plain columns were cast and tested. Half of the columns were wrapped with GFRP and the other half with CFRP. All columns were tested by applying an axial load at 50 mm eccentricity. In each group (GFRP or CFRP wrapped) of columns...

The behaviour of FRP wrapped HSC columns under different eccentric loads

The majority of columns are subjected to a combination of an axial load and a bending moment in one or two directions. With a few exceptions, most of the research in the area of FRP wrapped columns have concentrated on the behaviour of concentrically loaded columns. This paper presents results of testing nine reinforced high strength concrete columns. The column specimens are circular in shape ...

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...

Concrete Open-Wall Systems Wrapped with FRP under Torsional Loads

The static behavior of reinforced concrete (RC) beams plated with layers of fiber-reinforced composite material (FRP) is widely investigated in current literature, which deals with both its numerical modeling as well as experiments. Scientific interest in this topic is explained by the increasing widespread use of composite materials in retrofitting techniques, as well as the consolidation and ...
