“…In addition, field surveys on corrosion performance of RC members constructed with epoxy-coated reinforcing bars were also investigated [11][12][13][14][15][16][17][18][19][20][21][22]. Although the first evidence of unsatisfactory field performance of epoxy-coated bars emerged in 1986 in bridges of the Florida Keys [12], many field investigations reported good performance of the epoxy-coated bars.…”

“…Corrosion of steel reinforcement is a considerable issue in humid and aggressive areas and causes large maintenance cost and the loss of the performance of structural components [2,3]. Different methods such as the use of galvanised or stainless steel bars, epoxy coating and cathodic protection have been used to protect reinforcement from corrosion [4][5][6][7]. None of the methods, however, have fully eliminated the corrosion of steel reinforcement [8,9].…”

Fibre Reinforced Polymer (FRP) bars has attracted a significant amount of research attention in the last three decades to overcome the problems associated with the corrosion of steel reinforcing bars in reinforced concrete members. A limited number of studies, however, have investigated the behaviour of concrete columns reinforced with FRP bars. Also, available design standards either ignore the contribution of or do not recommend the use of GFRP bars in compression members. This study reports the results of experimental investigations of concrete specimens reinforced with GFRP bars and GFRP helices as longitudinal and transverse reinforcement, respectively. A total of five circular concrete columns of 205 mm in diameter and 800 mm in height were cast and tested under axial compression. The experimental results showed that reducing the spacing of the GFRP helices or confining the specimens with CFRP sheet led to improvements in the strength and ductility of the specimens. Also, an analytical model has been developed for the axial loadaxial deformation behaviour of the circular concrete columns reinforced with GFRP bars and helices. The model has been validated with the experimental results.

“…The cost of repair and restoration for the deteriorated structures due to corrosion of reinforcement can be significantly high. Many methods have been applied to protect reinforcement from corrosion including the use of galvanised or stainless steel bars, epoxy coating and cathodic protection [1][2][3][4]. However, none of these methods have provided a drastic solution to this problem [5].…”

This paper presents an innovative reinforcing scheme for concrete columns using glass fibre reinforced polymer (GFRP) tubes. GFRP tubes (solid and perforated) have been placed into concrete columns to provide reinforcement in both longitudinal and transverse directions. In this study, 14 columns with 150 mm diameter and 300 mm height have been cast and tested under axial compression. The columns have been divided into seven groups; each group contains two columns. The first group of columns are the reference columns without any reinforcement. The other six groups of columns are reinforced with solid and perforated (axially and diagonally) GFRP tubes. The test results show that GFRP tubes are effective in improving the strength and the ductility capacity of FRP (fibre reinforced polymer) Tube Reinforced Concrete (FTRC) columns. Also, perforated GFRP tubes have been found effective in integrating concrete core with concrete cover. However, axially perforated FTRC columns have been found most effective considering the strength and the ductility capacity of the concrete columns. In addition to the experimental investigations, numerical simulations have been carried out to assess the influence of tube perforations on the behaviour of FTRC columns. The simulation results show that reduction in the hole diameter, rather than increase in the vertical hole spacing, is the most effective in increasing the strength and the ductility capacity of FTRC columns. -----------------------------------------------------
