What is web shear cracking of concrete section?

Web shear cracking in concrete refers to the diagonal cracks that develop in the web of a reinforced concrete beam or slab, typically occurring under shear stress. These cracks are often a result of inadequate shear reinforcement or excessive load, leading to failure in the concrete's tensile capacity. Web shear cracks can compromise the structural integrity of the element and may require remedial measures to ensure safety and performance. Proper design and detailing of shear reinforcement can help mitigate this issue.
