Low-Cost Fiber Rope Reinforced Polymer (FRRP) Confinement of Square Columns with Different Corner Radii

repair of earthquake-damaged square r/c columns with glass fiber-reinforced polymer

this paper presents an experimental study on seismic repair of damaged square reinforced concrete columns with poor lap splices, 90-degree hooks and widely spaced transverse bars in plastic hinge regions according to aci detailing (pre.1971) and (318-02) using gfrp wraps. three specimens were tested in “as built” condition and retested after they were repaired by glass fiberreinforced plastic s...

Mechanical Characteristics of Low-cost Hybrid Fiber Reinforced Polymer

This report deals with the experimental investigation of using large deformable FRP, ± 45° oriented fibers, in concrete-filled fiber tubes (CFFT) under axial cyclic compressive loading. In addition, this report presents finite element modeling (FE) of CFFTs with large rupture strain FRP (LRS-FRP). The LRS-FRP is made with polyethylene naphthalate (PEN) and polyethylene terephthalate (PET) fiber...

Long-term Stability of Pultruded Glass Fiber-reinforced- Polymer Columns

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...

Effect of ply configuration on hollow square reinforced concrete columns confined with Carbon fibre-reinforced polymer (CFRP)

This paper presents results of testing twelve hollow square reinforced concrete specimens wrapped with Carbon fibre reinforced polymer CFRP. The effect of ply configuration on the behaviour of the specimens is investigated. All specimens were 800mm high and had the dimensions of 200mm× 200mm in cross-section and a hollow core of 80mm× 80mm. The specimens were divided into four groups with three...
