Fiber Reinforced Polymer (FRP) Confined Circular Concrete Columns: An Experimental Overview

چکیده
Fiber-reinforced polymers (FRPs) are widely used as composite materials in civil engineering applications to rehabilitate or strengthen reinforced-concrete structural elements. The purpose of this study was compile an extensive and up-to-date experimental database based on the compressive tests conducted circular confined concrete elements using FRP materials. Strict criteria were implemented during collection data minimize uncertainty maximize uniformity. In order compare results, collected divided into two categories type confinement, namely wrapped tube encased. A detailed 1470 test results FRP-confined cylindrical specimens demonstrated specimens’ geometry, jacketing materials’ physical mechanical properties, effect confinement axial strength strain. analysis led important observations parameters that influence concrete’s behavior. unconfined seems be inversely related efficiency. efficiency is quite limited high-strength specimens. Carbon fibers tend provide greater effectiveness, while rigidity found contribute significantly confinement. Glass aramid seem perform equally well, regardless method. An interesting finding FRP-wrapped similarly tube-encased terms increases strength, latter associated with larger ultimate strains.

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...
متن کاملTheoretical 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...
