Hi friends, Punching shear is a phenomenon in structural engineering which describes the failure of flat slabs due to concentrated loads, such as columns. Today, I’ll show you, what punching shear is and how you design and verify flat slabs for punching shear without and with punching reinforcement in 5 steps. If you prefer video, then you can check out my YouTube tutorial on punching shear design of reinforced concrete slabs (→ click here ←). If you liked the video, I would really appreciate...
