Punching shear is a type of failure that occurs in flat slabs or foundations when they are subjected to high concentrated loads, such as columns. The failure happens in a circular shape around the load, creating a cone-shaped perforation in the slab. This is a brittle and dangerous failure mode that requires careful design and verification
To prevent punching shear, engineers need to consider the following steps¹:
- Check if the concrete is strong enough alone;
- If not, check if the amount of reinforcement is reasonable;
- Design reinforcement if reasonable, if not, change the form of structure.
Some examples of reinforcement methods are using vertical bars, drop panels, or flared column heads². Alternatively, some codes of practice may allow more liberal design assumptions
Punching shear is a complex phenomenon that involves many factors, such as slab thickness, column size, load magnitude, concrete strength, and reinforcement ratio. To accurately predict the punching shear strength and design the appropriate reinforcement, engineers need to use advanced methods, such as the finite element method
