N2 - Forty-five glass fiber reinforced polymer (GFRP) rebars were tested in compression to determine their ultimate strength and Young's modulus. The rebars (or C-bars), produced by Marshall Industries Composites, Inc., had an outside diameter of 15 mm (#15 rebar), and unbraced lengths varying from 50 to 380 mm.

Many studies have corroborated the use of Stainless Steel Reinforcements (SSR) for structures in corrosive environments. However, even though the conditions for their employment are specified in different standards, their use is always tied to the same requirements for standard carbon steel rebars (B500SD), among which an equivalent carbon content for …

However, when l b exceeds 10d, the tensile load could reach the peak load of rebars, resulting in a P/P y ratio of 1.27, which closely corresponds to the strength-to-yield ratio of the rebar (f u /f y = 1.35). This indicates that the ultimate tensile load is governed by the strength of steel rebars, ...

All of the existing works on continuous EPC beams were focused on the usage of steel rebars, except for a recent work of Lou et al. [18] on redistribution of moments. Lou et al. [18] examined the rebar influence on the redistribution behavior in continuous EPC beams by applying a computer model. The results demonstrated that because of the non-occurrence of plastic …

For Specimens A1 and A2, l p ' is set to 222.5 mm; for Specimens A3 and A4, l p ' is empirically set to 500 mm. This is because the deformation capacity of Specimens A3 and A4 was larger than that of Specimens A1 and A2, respectively, as depicted by the load-displacement curves presented in Fig. 8. Actually, the deformation capacity of the ...

The residual mechanical properties of rebars with significant localized corrosion pits are challenging to accurately quantify with only μ mass.For the ultimate tensile capacity of pitting rebars, it is often governed by the most severely corroded section inside the pit and can be roughly estimated by the maximum cross-sectional area loss rate μ max (i.e., 1-A min /A 0).

For P-BFRP rebars, no obvious peak appeared on the tan δ curve. It might be that the peak has not yet been reached due to the measurement limit of the instrument (550 °C). P-BFRP rebars exhibited the lowest tan δ values and the lowest area below the curve, which indicates a minimum degree of molecular motion and energy dissipation. Therefore ...

The increase in bond stress of TMT rebars of 8 mm diameter compared to TMT of 12 mm rebars were around 246%, 110%, 36% and 11% for slips of 0.01 mm, 0.1 mm 0.025 mm and 0.25 mm respectively. However, the increase in bond strength for HYSD rebars of 10 mm diameter was negligible when compared to HYSD 12 mm diameter rebars.

Employing corrosion-resistant materials is a strategy that can mitigate corrosion damage in rebars. Stainless steel rebars [12] and stainless steel clad rebars [13] are typically employed in environments with high corrosive potential and where maintaining structural integrity is paramount. Alloying elements such as nickel lend these rebars their corrosion resistance [12].

The protruding ribs on rebars help anchor them within the concrete, allowing effective transfer of stresses between the rebar and concrete. This stress transfer mechanism relies on the bond between the deformed rebar surface and the surrounding concrete. The ribs create a mechanical interlock, preventing the rebar from being pulled out when ...
