Hi, I have a problem, I'm trying to import an IFC file exported from Tekla, which contains a beam with rebars. Well, when I imported it in Navisworks the prgram does not import the rebars but just the beam. I have tried playing with the options -> File readers -> IFC, but it does not help. I have also opened the same file with other viewers such as Solibri and Tekla …

To investigate the corrosion behavior of steel rebars in concrete, accelerated corrosion tests are often used [[25], [26], [27]]. In the conventional accelerated corrosion tests, such as the applying galvanostatic electrolysis and the cyclic corrosion test (CCT), the corrosion of steel rebars which initiates a crack on the concrete surface can be achieved in a few months …

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).

FRP rebars in particular present an attractive alternative to steel rebars in reinforced concrete. Among the features of this type of rebar are the high strength-to-weight ratio and potential resistance to aggressive environmental factors. This paper presents the results of an experimental and analytical study on the durability of E-glass FRP ...

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 ...

Traditionally, reinforced concrete structures are constructed using steel rebars as reinforcement which is more susceptible to reinforcement corrosion in severe exposure conditions. This leads to many disadvantages, like deterioration of concrete, reduction in strength, and increase in maintenance costs, which leads to a decrease in the serviceability of critical infrastructure.

Results show that bond strength of G F R P rebars at 0.1 and 0.2 mm slippage is approximately 56-76% and 80-97% of the maximum bond strength, respectively. Similarly, it is approximately 36-89% and 50-99% for steel rebars, depending on the rebar diameter. They also show that, as for the steel rebar, bond strength decreases as the bar diameter ...

Accelerated corrosion tests showed that uncoated rebars had a mass loss of about 3.793 ± 0.266 %, while all coated rebars exhibited negligible mass loss. However, coated rebars experienced a reduction in bond strength: KC-R and FR-R coatings resulted in 16.3 % and 48 % reductions, respectively, whereas MC-R showed the least reduction at 9.4 %.
