RTI Research Project # demonstrated the feasibility of using carbon fiber reinforced polymer (CFRP) for shear strengthening of large bridge girders or supporting elements.   However, limited research work has been conducted to examine the axial behavior of concrete columns reinforced with FRP bars. In this paper, the behavior and compression strength of 11 full-scale circular concrete columns reinforced with carbon fiber–reinforced polymer (CFRP.

Objective: The aim of the present research is to investigate the application and durability of historical circular masonry stone columns completely strengthened by carbon fiber reinforced polymer Author: Sayed Hemeda. Abstract. Retrofitting circular and rectangular concrete columns with Carbon Fiber Reinforced Polymer (CFRP) has been proven to be a method of increasing the ultimate confined compressive strength $$f^{\prime}_{cc}$$.The present study uses a hybrid of Analytic Hierarchy Process (AHP) and Backpropagation Artificial Neural Networks (BP) that assesses the strength performance of circular Author: Jason Ongpeng, Isabel Nicole Lecciones, Jasmine Anne Garduque, Daniel Joshua Buera.

Most concrete has some embedded steel reinforcement. If the steel is being counted on to provide bending or tensile strength— if the structural element is intended to behave as a composite—we call it reinforced concrete. But even so-called plain concrete, where we are counting on the concrete . The fracture toughness of carbon fiber reinforced plastics is governed by the following mechanisms: 1) debonding between the carbon fiber and polymer matrix, 2) fiber pull-out, and 3) delamination .

### Reinforcement of circular concrete columns with carbon fiber reinforced polymer (CFRP) jackets by Burt K. Purba Download PDF EPUB FB2

The use of steel bars as reinforcement is not preferred in some concrete structures because steel causes corrosion or electric magnetic field problems.

One of the best alternatives to steel bars is carbon fibre-reinforced polymer (CFRP) bars. The experimental program consisted of 18 reinforced rectangular concrete columns Author: Zrar Sedeeq Othman, Ahmed Heidayet Mohammad.

This paper presents the results of an experimental study on the use of carbon fiber–reinforced polymer sheets as reinforcement for the rotational behavior of bolted glulam beam-to-column connections. Monotonic loading was applied on connection specimens to identify their stiffness, ductility, and maximum moment resistance values.

This study describes how carbon fiber reinforced polymer jackets can be used to reinforce circular concrete columns.

Fibers aligned in the circumferential direction provide axial and shear strength to the concrete, while fibers aligned in the longitudinal direction provide flexural by: A 3-D nonlinear finite element model of FRP reinforced Column model has xmm cross-section and m height.

The column specimens were shown in table 1. Table 1: Properties of column specimens Analysis of concrete columns Reinforced by Fiber Reinforced File Size: KB. The study reported herein investigates the use of carbon fiber-reinforced polymer (CFRP) composite jackets as a method of retrofitting existing nonductile reinforced concrete building columns.

The most common defects of these structures are the damaged protective concrete layer and the corroded steel reinforcement. The reinforced concrete columns with a circular cross section are commonly used in the construction of buildings, ports and bridges (Fig.

In this study, 68 reinforced concrete columns were tested under uniaxial compression after being jacketed externally with carbon fiber-reinforced polymer (CFRP) sheets. Forty specimens were cast using low strength concrete and inadequate internal transverse reinforcement, while 28 specimens were cast with medium strength concrete and adequate internal transverse reinforcement.

Fiber-Reinforced Polymer (FRP) materials are composite materials that typically consist of strong fibers embedded in a resin matrix. The fibers provide strength and stiffness to the composite and generally carry most of the applied loads.

The matrix acts to bond and protect the fibers and to provide for transfer of stress from fiber to fiber. An analytical model is introduced in this paper to predict the stress–strain behavior of axially loaded circular reinforced concrete (RC) columns with internal longitudinal reinforcement and lateral ties confined by carbon fiber‐reinforced polymer Cited by: 1.

Fibre-reinforced polymer (FRP) reinforcement has been used in construction as either internal or external reinforcement for concrete structures in the past decade. This book provides the latest research findings related to the development, design and application of FRP reinforcement.

Fiber-reinforced polymer (FRP) bars have emerged as an effective alternative for providing shear and flex-ural reinforcement for reinforced concrete (RC) members in different applications.

In this paper, the behavior and compression strength of 11 full-scale circular concrete columns reinforced with carbon fiber–reinforced polymer (CFRP) bars and spirals were investigated. The application of glass fiber reinforced polymer (GFRP) reinforcement in concrete structures, has encountering an increasing interest worldwide, for several applications in civil engineering.

A high strength Carbon fiber reinforced polymer (CFRP) SikaWrap® FX C (NSM-CFRP rope) manufactured by SIKA was used in this study to repair the RC circular column specimens. This material was installed to repair column. L.C. Hollaway, in Service Life Estimation and Extension of Civil Engineering Structures, Strengthening of RC columns.

Reinforced concrete circular columns may require strengthening (i) in seismic regions, (ii) due to upgrading the columns or (iii) due to insufficient transverse reinforcement in the columns that will cause premature shear failure and brittle crushing of the concrete.

The number of these tests, however, is much less than similar ones performed on reinforced-concrete columns without fiber-reinforced polymer confinement. This paper presents cyclic flexural test on reinforced-concrete columns confined with conventional circular hoops and carbon fiber–reinforced polymer.

Innovative reinforcement as fiber-reinforced polymer (FRP) bars has been proposed as alternative for the substitution of the traditional steel bars in reinforced concrete (RC) structures. Although the advantages of this polymer reinforcement Cited by: 6.
