“…[42,43]). This is due to the dependency of the strain enhancement ratio (ε cu / ε co ) to the ultimate tensile strain of the material (ε f or ε frp ), in addition to the confinement ratio (f lu,a / f' co ), as was pointed out in a number of previous studies [3,18,37,39].…”

“…In the work of Ozbakkaloglu et al [6], an exhaustive critical review of 59 design-oriented models was performed. It was concluded that the models developed by Lam and Teng [11] and Tamuzs et al [30] are the most accurate for predicting, respectively, the ultimate strength and the ultimate axial strain of confined concrete. In the work of Ozbakkaloglu et al [6] were contemplated the prediction of 832 test results, leading to average errors of 11.8% for the first model and 26.3% for the second [7].…”

The main goal of the study herein described was to evaluate the performance of an innovative confining unidirectional hybrid FRP solution for circular concrete columns, exploiting the hybrid effect and pseudo-ductility of FRP jackets made of different fibres. First, an experimental study on the compressive stress-strain curves of small-scale plain circular concrete columns confined with hybrid FRP was conducted. Jackets were produced with dry unidirectional fabrics of high-modulus carbon, standard-modulus carbon, E-glass, and basalt. Different combinations were tested, varying the number of layers of each material. Next, two new simple design-oriented models were developed in order to predict the compressive peak stress of compressed concrete columns confined with hybrid FRP jacketing. Predictions were in close agreement with test results. Finally, an existing analysisoriented model developed for non-hybrid FRP-confined concrete was adapted to also predict dilation and the compressive stress-strain curve of hybrid FRP-confined concrete. Likewise, predictions were in close agreement with test results. It was concluded that hybridisation can effectively contribute to maximize the lateral strain efficiency of FRP jacketing and its behaviour can be predicted with the developed analytical models.

“…Fiber Reinforced Polymers (FRP) has been widely recognized as popular materials for the repair or reinforcement of concrete structures. Many studies have been carried out to test the effectiveness of FRP in strengthening / improving the existing concrete structures and the results of these studies have confirmed that the strength and ductility of concrete confined by FRP is significantly improve [3][4][5][6][7][8]. Therefore FRP can also be used to strengthen the lightweight concrete for structural applications.…”

This paper presents the results of an experimental study that was undertaken to investigate the effects of the number of FRP layer on the compressive behavior of fiberreinforced polymer-Confined Lightweight Concrete Columns (FCLCs). A total of 6 lightweight concrete were manufactured and tested under axial compression. The results indicate lightweight concrete in a FCLCs system is confined effectively by FRP. The results also suggest that increasing the number of FRP layer leads to an increase in the ultimate axial stress and strain of concrete FCLCs.
