Introduce the required values and press the "Calculate" button to get the concrete shear resistance and the utilisation ratio of the section.

concrete shear resistance verification

Explanation

When applying a perpendicular load to the beam’s guideline, shear loads appear parallel to the beam’s transversal section. The resistant scheme of a concrete beam to shear loads cannot be considered bidimensional but three dimensional. The procedures that have been adopted by the different concrete manuals to calculate the shear resistance admit that the transversal reinforcement contribution is the one that results from the Ritter-Mörsch truss analogy. The image below shows how the cracks produced by shear look like. These cracks usually go from the tensioned reinforcement to the load applying point.
