Experimental investigation of axial strength of damaged concrete-filled FRP tubes

Axial compressive strength of circular concrete-filled fiber-reinforced polymer (FRP) tubes (CFFTs) benefits greatly from a significant concrete confinement by the tube. Accidentally or deliberately induced damage to the tube would undermine the CFFT strength. In this study 33 CFFT short columns of 144–168 mm (5.67–6.61 in.) outer diameter (D) and 420–460 mm (16.53–18.11 in) height (H)(ie H/D= 2.74–2.92) were tested under concentric loading to failure. Tube damage was artificially induced in the form of through-thickness linear cuts at mid-height. The cut length (x) and orientation (θ) with respect to the longitudinal axis were varied. Two types of GFRP tubes were studied, namely a nominal [±55 o] angle-ply tube with diameter-to-thickness ratio (D/t)= 35 and a [86°/− 12°] near cross-ply with D/t= 48, to investigate two commonly available but distinctly different tubes. The effect of cuts in the two tubes studied was …

Axial Capacity of Concrete Filled GFRP Tubes with Simulated Tube Damage

Concrete-filled fiber-reinforced polymer (FRP) tube (CFFT) systems have attracted much attention over the past several decades due to their superior features including ease and speed of construction, strength, ductility, and durability. This study aims at understanding the effect of tube damage on the axial behavior and strength of CFFTs. A test program was conducted on two types of tubes, namely, a near cross-ply and an angle-ply glass-FRP (GFRP) tubes. The damage was simulated as a vertical cut of different lengths throughout the full thickness of the tubes. A comparison with undamaged CFFTs and plain concrete specimens was included. The undamaged CFFTs had an axial strength double that of the plain concrete core because of the confinement effect and some axial load sharing of the tube. For damaged CFFTs, test results demonstrated a correlation between the reduced axial strength and length of cut …

Assessment of Confinement Models and Minimum Volumetric Ratio for Glass Fiber-Reinforced Polymer-Reinforced Concrete Circular Columns.

The design provisions of reinforced concrete (RC) circular columns in ACI 318 are based on the work done by ACI Committee 105 in 1933 for steel spiral reinforcement. The provisions for volumetric reinforcement ratio and spacing were intended to ensure sufficient confinement after spalling of the concrete cover. This paper presents the development of similar provisions for columns reinforced with glass fiber-reinforced polymer (GFRP) reinforcing bar and spirals that could be adopted in the upcoming version of the ACI 440.1 R design guide. A comprehensive database of 56 experiments on concentrically loaded circular columns reinforced with GFRP was assembled from 12 studies with a wider range of parameters. The analysis carried out focused on the confined concrete strength and considered the softening response of the concrete cover, which was presumably omitted in the reported data. An assessment of …

Confinement model for FRP-wrapped circular columns when the wraps are subjected to damage

Fiber-reinforced polymer (FRP) wrapped concrete columns are vulnerable to accidental damage or vandalism, which may cause physical cuts or tearing of the jacket, thereby compromising the confined strength and ductility of the column. This paper aims at providing a simple tool to reassess the strength under a given level of damage. Finite element (FE) models were developed to examine a variety of cuts in the FRP jacket and develop a confinement model including the damage effects. After validation with 37 experimental tests from literature, the FE model was used in a comprehensive parametric analysis, examining different geometric and material variables, namely: cut orientation (longitudinal or circumferential); cut length and location, diameter-to-jacket thickness ratio, multiple cuts, concrete strength, and FRP elastic modulus. Results of the numerical models were analyzed using multiple nonlinear …

Performance of Innovative Precast Concrete Sleepers Prestressed with Glass Fiber-Reinforced Polymer Reinforcing Bars.

Replacing defective reinforced concrete railway sleepers has reportedly been urged by several businesses and maintenance agencies. The harsh environmental conditions, especially in North America, trigger material degradation and steel corrosion. Glass fiber-reinforced polymer (GFRP) bars have been increasingly used in a wide variety of applications. The present study presents an original, promising application of GFRP as prestressed reinforcement in concrete railway sleepers. For prestressed GFRP sleepers to be accepted as replacements for defective sleepers made with timber and concrete, they must pass several short-and long-term tests. Full-scale GFRP-and steel-reinforced concrete sleepers were designed, tested, and compared according to the requirements of the American Railway Engineering and Maintenance-of-Way Association (AREMA). The test results show that GFRP-and steel-reinforced …

Testing, design, and field implementation of GFRP RC soft-eyes for tunnel construction

The use of fiber-reinforced polymer (FRP)-reinforced concrete (RC) soft-eyes in tunnel constructions has been gaining noticeable popularity as a successful and practical application of the non-corrosive FRP reinforcement. This unique use of FRP bars takes advantage of their anisotropic property, meaning they are strong along the main axis but can be machined, abraded away, or consumed by tunnel boring machines (TBMs). Consequently, the research program herein offers an inclusive experimental database followed by a detailed theoretical analysis and design provisions for FRP-RC soft-eyes subjected to either axial, flexural, combined axial and flexural loads, or shear stresses. The experimental evidence from our study accentuated the feasibility of FRP reinforcement to maintain strength and stability of FRP-RC elements against all various applied loads. In addition, this paper provides a summary of three …

Torsion in concrete beams reinforced with GFRP spirals

Current FRP guidelines do not have enough evidence on the torsional performance of beams reinforced with glass fiber-reinforced polymer (GFRP) reinforcement due to the lack of research and complexity of the problem. A review of the past work was presented in the state-of-the-art section to stand on mile-stone prospective considering the variety and development of GFRP manufacturing. This study examined the rectangular spirals and rectilinear stirrups to reinforce concrete beams in the transverse direction under pure torsion loading. The test parameters included four levels of transverse reinforcement ratio and the type of transverse reinforcement in terms of rectilinear stirrups vs. spirals. The test results demonstrated that rectangular GFRP spirals provided superior tensile resistance required to develop high ultimate torsional moments after cracking and hence can be effectively used. The failure of the tested …
