Question

P

Correct answer (C) [figure] Solution Bond stress is the shear stress acting on the surface of the reinforcing bar that provides the transfer of force between the steel and concrete. In a pull-out test (where a bar is pulled from a concrete block), the slip is maximum at the loaded end and decreases along the embedded length. Consequently, the bond stress is highest at the point of entry (loaded end) and decays non-linearly towards the far end of the bar. Option (C) correctly depicts this non-linear distribution starting from a maximum at the loaded end. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
