More fundamentally, little has been said about the distribution of bonding electrons in terms of orbitals, although it has been shown that in atoms the distributions of electrons are described by wavefunctions.
It refers to the distribution of bonded dye molecules on the fiber surface.
The distribution of bond stress is more uniform for the specimen with a large corrosion-induced crack width.
The value of 1/n, which is related to the distribution of bonded ions on the adsorbent surface, represents beneficial adsorption if it is between 0.1 and 1.
The value of n, which is related to the distribution of bonded ions on the sorbent surface, represents beneficial adsorption if it is between 1 and 10.
The σ2 for this shell was 0.02 Å2 reflecting the high distribution of bond distances for this shell as compared to the other shells.
This decrease was associated with the calculation of bond strength assuming constant bond stress distribution while higher non-linear distribution of bond stresses normally happened with longer embedded length in concrete.
Results from pull out testing show that bond strength decreases with increased embedment length suggesting a non-uniform distribution of bond strengths.
The bond stress is the difference between the concrete and rebar in terms of tensile deformation such that the bond stress can be written as Eq. (1): Open image in new window Fig. 11 Distribution of bond stress.
Finally, based on the distribution of bond stress along the embedded length, the anchorage position function was ascertained and then an accurate bond slip relationship was built, which was significant in structural design and numerical simulation.
In addition, some specimens were instrumented, with internal strain gauges in the reinforcing bar to provide data on the reinforcement strain, thus allowing the distribution of bond stresses and their evolution during sustained loading to be also presented and analysed.
