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 ...

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 …

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 …

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 %.

For the splice samples, two kinds of failure modes were identified: the pullout of GFRP rebars (P) and the splitting of UHPC (S), as outlined in Table 1. The observed failure modes met the typical scenarios expected in structural design, rather than focusing on the specific failure of the bars themselves.
