What is minimum shear reinforcement?
The minimum shear reinforcement is a function of the compressive strength of concrete, the shear span-to-depth ratio and the percentage of the flexural reinforcement as shown in Eq.
Why minimum shear reinforcement is provided?
The minimum shear reinforcement is provided for the following: (i) Any sudden failure of beams is prevented if concrete cover bursts and the bond to the tension steel is lost. (ii) Brittle shear failure is arrested which would have occurred without shear reinforcement.
How do I get reinforcement details on Etabs?

What causes shear stress?
shear stress, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress. The resultant shear is of great importance in nature, being intimately related to the downslope movement of earth materials and to earthquakes.
What is shear tension failure?
Shear failure occurs when the beam has shear resistance lower than flexural strength and the shear force exceeds the shear capacity of different materials of the beam. A shear load is a force that tends to produce a sliding failure on a material along a plane that is parallel to the direction of the force.
What should be provided if the shear force due to ultimate load is less than the shear force of the concrete?
Explanation: When V the shear force due to ultimate loads is less than the shear force of the concrete vc, the shear force which can be carried by the concrete, a minimum shear reinforcement should be provided in the form of stirrups with spacing.
Where is shear reinforcement required?
What is shear reinforcement? Shear reinforcement is designed to resist shear forces in excess of the shear strength of concrete. They are provided in forms of vertical or inclined stirrups or longitudinal reinforcement bent up at 45 degrees at locations where they are no longer needed to resist bending.
