bond stress

bond stress

1. The force of adhesion per unit area of contact between two bonded surfaces, such as between concrete and a steel reinforcing bar.
2. The shear stress at the surface of a reinforcing bar which prevents relative movement between the bar and the surrounding concrete.

The force transferred from the concrete to the reinforcing steel was calculated using Equation (1), while the bond stress which occured in the reinforcing steel element was obtained by Equation (2).
The bond stress was determined using the detachment method or pull-out of the fiber in tension (Valadez, 1999), according to equation 1.
3] is the group reduction factor associated with the number of fibres pulling out per unit area; [tau] is the average bond stress of a single fibre embedded in the concrete; [V.
where [alpha]--coefficient representing the shape factor of the bond stress distribution along the transfer zone: [alpha] = 2 for uniform bond stress distribution (linear variation in strand stress); [alpha] = 3 for linear descending bond stress distribution (parabolic variation in strand stress); [f.
The bond stress at the de-bonded zone is kept as the reduced value of the bond strength considering the bond condition of the de-bonded zone.
Based on this idealized bond stress distribution, it was expected that AE events are created when a certain stress threshold is crossed along the embedment length ([l.
Stresses predicted by bond stress analysis and lap shear strength as a function of adhesive modulus.
The most recent consolidated cash flow statement, which reflects transactions through the 2012 series E&F bonds, demonstrates that the program's asset parity position, in various interest-rate and bank bond stress scenarios, is projected to stay above 112%.
Furthermore where, q1, q2 and qy1, qy2 are the bond stress and the yield stress of the first and second layers respectively.
In the vicinity of cracks, reinforcement slip occurs and bond stress develops between the reinforcing bar and surrounding concrete, transmitting tensile force from the bar to concrete.
In a study on the effect of mix proportion and reinforcement size on the anchorage bond stress of laterized concrete; Osunade and Babalola [8] established that both mix proportion and the size of reinforcement have a significant effect on the anchorage bond stress of laterized concrete specimens.
While those behind the North East Enterprise Bond stress that its success will be hard to quantify, they believe it will have a real effect on the region.
