Behavior and model evaluation of large-rupture-strain (LRS) FRP-confined concrete-encased high-strength steel columns under axial compression

De-Hua Zhu et al.

Summary: The axial compressive behavior of FCSCs with a PET FRP tube were investigated in this study. The results showed that the steel strength can be fully utilized due to the suppression of local instability by the concrete. Circular steel tube specimens performed better than cruciform steel specimens. Model predictions by Lin et al. and Zeng et al. were relatively satisfactory for the ultimate stress and strain of confined concrete in PFCSCs.

Shear behavior of FRP-UHPC tubular beams

Jun-Jie Zeng et al.

Summary: This study proposed tubular beams made of FRP grid-reinforced UHPC composites (FUC) and investigated the shear behavior of ten FUC tubular beams under shear loading. The effects of shear span ratio and fiber type on the shear behavior were analyzed. It was found that FUC tubular beams exhibited excellent ultimate strength and ductility under shear, and a theoretical model based on the truss-arch theory accurately predicted their shear capacity.

Compressive behavior of PET FRP-confined concrete encased CFST columns

Jie-Kai Zhou et al.

Summary: This study tests ten novel circular PFCECs with various parameters to investigate their axial compressive behavior. The results show that the load-carrying capacity of PFCECs increases with the diameter ratio, but ultimate axial strains and residual axial loads do not necessarily increase. Existing models can predict the ultimate axial stresses/strains accurately, but not the complete axial stress-axial strain responses of PFCECs.

Bond strength of GFRP bars to high strength and ultra-high strength fiber reinforced seawater sea-sand concrete (SSC)

Jinjing Liao et al.

Summary: The study investigated the bond strength of glass fiber reinforced polymer bars in sea-sand concrete, finding that substitution of sea sand and seawater for normal concrete had no significant impact on short-term bond strength. Additionally, increasing the concrete strength and polyethylene fiber content improved bond strength, while increasing the embedment length of the bar resulted in decreased bond strength.

Summary: This study developed a new design-oriented stress-strain model to predict the stress-strain relationship of FRP-confined UHPC cylinders under axial compression. The model accurately estimated characteristic stresses and strains and showed good agreement with most of the test results, filling the research gap in this area.

Durability assessment of PEN/PET FRP composites based on accelerated aging in alkaline solution/seawater with different temperatures

Jun-Jie Zeng et al.

Summary: This study conducted durability tests on 282 LRS FRP sheets and found that the changes in elastic modulus for PEN FRP sheets after aging at different temperatures were minor. The degradation rate of tensile strength was around 10%, and the degradation rate of tensile rupture strain was around 12.5% for PEN FRP sheets aged in 60°C solutions for 365 days. Additionally, higher exposure temperatures led to a significant decrease in the tensile strength of LRS FRP composites. The durability of PEN FRP sheets was more affected in alkaline environments compared to seawater environments, and PEN FRP composites showed better alkaline resistance than PET FRP composites.

Large-rupture-strain (LRS) FRP-confined concrete in square stub columns: Effects of specimen size and assessments of existing models

Jun-Jie Zeng et al.

Summary: Polyethylene terephthalate (PET) fiber reinforced polymer (FRP) is an environmentally friendly material with high rupture strain capacity, and it has promising applications in various industries. This study focuses on understanding the confinement mechanism of PET FRP-confined concrete in square stub columns through axial compression tests. The influences of confinement thickness, corner radius, and specimen size were investigated. The results showed that specimen size is not significant for small and medium-sized columns with similar confinement levels.

Stress-strain behavior and design-oriented model for FRP spiral strip-confined concrete

JinJing Liao et al.

Summary: Partial fiber-reinforced polymer (FRP) wrapping is an effective technique for strengthening reinforced concrete (RC) columns. In this study, the confinement mechanism of FRP spiral strip-wrapped concrete columns is investigated through axial compression tests. The results show that the proposed confinement effectiveness factor significantly affects the ultimate axial stress and the slope of the axial stress-strain curve. A new design-oriented stress-strain model is proposed based on the test data, which demonstrates good accuracy and robustness.

Flexural behavior of FRP grid reinforced ultra-high-performance concrete composite plates with different types of fibers

Jun-Jie Zeng et al.

Summary: Ultra-high performance concrete (UHPC) has gained popularity in structural engineering due to its excellent compressive strength and durability. However, its tensile property is inferior, thus requiring appropriate reinforcing materials. In this study, fiber-reinforced polymer (FRP) grids were used as reinforcements for UHPC plates, and the effects of fiber type, content, and length on the flexural behavior were investigated.

Compressive behavior of FRP-confined ultra-high performance concrete (UHPC) in circular columns

Jinjing Liao et al.

Summary: Through axial compression tests on FRP-confined UHPC, it was found that increasing steel fiber content can improve ductility and stress-strain behavior of the material. Different variables such as steel fiber content, specimen sizes, FRP fiber types, and FRP thickness were investigated for their influence on the compressive behavior. The results also showed that the type of FRP confinement fiber had limited influence on the stress-strain behavior of the specimens.

Summary: The study proposes the use of FRP jackets to strengthen ECFST columns, with experimental results showing that increasing FRP thickness enhances the elastic stiffness and ultimate axial load of the columns; the performance of FCECFST columns is significantly better than conventional ECFST columns. A new model for ultimate axial stress and strain is introduced, with verification demonstrating its accuracy.

Summary: The study found that increasing the use of FRP and steel tubes has a significant impact on the axial compressive behavior of HFSCTs, and different confinement materials have different effects on the ultimate stress and ultimate deformation ability of specimens. Additionally, a test database for concrete-filled circular FRP-steel composite tube columns was established by collecting data from 155 samples.
