Behavior of Circular Reinforced Concrete Columns Confined with CFRP Composites

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...

Yield curvature for seismic design of circular reinforced concrete columns

Rehabilitation of Reinforced Concrete Columns

In recent years, rehabilitation has been the subject of extensive research due to increased spending on building work and repair of built works. In all cases, it is absolutely essential to carry out methods of strengthening or repair of structural elements, and that following an inspection analysis and methodology of a correct diagnosis. The reinforced concrete columns are important elements in...

Behavior of FRP-Confined Concrete-Filled Steel Tube Columns

This paper presents the results of an experimental study into the behavior of concrete-filled steel tube columns confined by fiber-reinforced polymer (FRP). Eleven columns were tested to investigate the effects of the FRP layer number, the thickness of the steel tube and concrete strength on their load capacity and axial deformation capacity. The experimental results indicated that the FRP wrap...
