Response of concrete columns reinforced with longitudinal and transverse BFRP bars under concentric and eccentric loading

Nouran ElMessalami et al.

Summary: This study found that reducing the spacing of BFRP ties improved the ductility and confinement efficiency of BFRP-reinforced concrete columns, while reducing ties' spacing had an insignificant effect on the load-carrying capacities of the columns and the contribution of longitudinal bars.

Efficiency of GFRP bars and hoops in recycled aggregate concrete columns: Experimental and numerical study

Ali Raza et al.

Summary: Through experimentation and simulation analysis of GFRP-reinforced recycled aggregate concrete columns and steel-reinforced recycled aggregate concrete columns, it was found that while GFRP-reinforced columns have lower axial strength, they exhibit higher ductility indices. There is good consistency observed among the experimental results, numerical simulations, and theoretical predictions for GRAC columns.

Influence of synthetic fibers on the seismic behavior of reinforced-concrete circular columns

Jesus Emilio Rivera et al.

Summary: The study examined the behavior of large-scale synthetic fiber-reinforced concrete columns under constant axial load and reversed flexure, showing slightly improved cyclic behavior compared to columns with spiral transverse reinforcement. The enhanced performance of synthetic fiber-reinforced concrete can be achieved with practical transverse steel reinforcement spacings, providing similar ductile behavior with reduced reinforcement and the addition of synthetic fibers. Difficulty in placing synthetic fiber-reinforced concrete in congested columns limits its use in columns with spacing less than 75mm until self-leveling concrete with a large amount of synthetic fibers is developed.

Effect of Using GFRP Reinforcement on the Behavior of Hollow-Core Circular Concrete Columns

Muhammad N. S. Hadi et al.

Summary: Glass fiber-reinforced polymer (GFRP) bar- and helix-reinforced hollow-core circular concrete columns exhibited higher effectiveness of confinement reinforcement and ductility compared to steel reinforcement. The GFRP bar-reinforced specimen with smaller pitch helices achieved significantly higher levels of confinement reinforcement effectiveness and ductility.

Axial performance of hybrid fiber reinforced concrete columns having GFRP longitudinal bars and spirals

Ali Raza et al.

Summary: The study investigated the behavior of GFRP-reinforced concrete columns with hybrid fibers, comparing GHC columns with SHC columns in terms of axial strength and ductility. It was found that GHC columns had lower axial strength but higher ductility compared to SHC columns, with both showing similar failure modes. Eccentric loading led to significant decrease in axial strength of all columns. A theoretical analysis proposed a new equation for predicting the axial strength of GHC columns based on the influence of GFRP bars and confining mechanism of GFRP spirals.

Concrete Columns Reinforced with GFRP and BFRP Bars under Concentric and Eccentric Loads: Experimental Testing and Analytical Investigation

Nouran Elmesalami et al.

Summary: The study tested twelve concrete columns reinforced with FRP bars under concentric and eccentric loadings, finding that columns reinforced with BFRP and GFRP had similar load-carrying capacities, lower than their steel-reinforced counterparts, with a more pronounced impact of increasing reinforcement ratio on eccentric columns. The contribution of GFRP and BFRP bars to column capacity was similar, while ignoring the strength contribution of FRP bars in design codes may lead to conservative predictions.

Cyclic stress-strain model for large-rupture strain fiber-reinforced polymer (LRS FRP)-confined concrete

Yu-Lei Bai et al.

Summary: LRS FRP-confined concrete enhances the ultimate strength, ductility, and energy absorption capacity of concrete structures. The confining pressure at large deformation significantly affects the damage process of concrete. By analyzing the cyclic response, plastic strain and stress degradation were identified as key parameters influencing the behavior of LRS FRP-confined concrete.

Reliability analysis of strength models for short-concrete columns under concentric loading with FRP rebars through Artificial Neural Network

Afaq Ahmad et al.

Summary: The utilization of fiber-reinforced polymers (FRP) in concrete columns has increased over the past decade, with researchers proposing equations to understand their load-carrying capacity. However, there are reservations in current design practices regarding the use of FRP bars as main reinforcement in columns. A study using Artificial Neural Network models and a new proposed equation aims to provide reliability analysis of physical models in predicting the effect of FRP in columns under concentric loading at the ultimate limit state. Results show that the ANN model and proposed equation yield closer results to experimental values compared to counterpart physical models.

Structural Behavior of GFRP-Reinforced Circular HFRC Columns Under Concentric and Eccentric Loading

Ali Raza et al.

Summary: This study compares the structural behavior of steel-reinforced concrete columns and GFRP-reinforced concrete columns with hybrid fibers, showing that SHFC columns have better axial strength and ultimate deflections while GHFC columns exhibit higher ductility indices. The failure modes and reductions in axial strength under eccentricities are similar between steel and GHFC columns. The newly developed empirical model for predicting the axial strength of GHFC columns shows close agreement with experimental results, supporting the proposed model's application.
