How to Check Punching Shear in a Concrete Slab: Worked Example with ACI 318-19
Punching shear is one of the most critical failure modes in reinforced concrete flat slabs. It occurs at columns and concentrated loads where the slab can “punch through” in a cone-shaped pattern — and when it fails, it fails suddenly. Here’s how to check it properly using ACI 318-19, step by step. What Is Punching … Read more
