Question

A dapped-end bearing connection in a precast concrete beam is shown. reinforcement bars The function of the indicated reinforcement bars is primarily to resist & O (A) bending caused by the eccentricity of the vertical reaction O (B) shear-friction reinforcement (C) confinement to prevent compression failure O (D) diagonal tension cracking emanating from the reentrant corner

Answer 1

Ans : D) Diagonal tension cracking emanating from the reentrant corner is the function of the indicated reinforcement bars . usually a reinforcement bars are used to provide ductility so that it ability to resist tension increases . As concrete can resist high compressive stresses but fails in tension and brittle , therefore it avoids diagonal tension cracking .
