Punching shear is a phenomenon that occurs in reinforced concrete slabs or footings when there is a concentrated load or reaction near a column or support, causing a shear failure. It typically happens when the load exceeds the capacity of the concrete to resist the shear forces, resulting in a failure mechanism resembling a cone-shaped "punching" through the slab.
****To prevent punching shear in current buildings or during the design stage, the following measures can be taken:
+ Adequate slab thickness: Design the slab with sufficient thickness to resist the anticipated punching shear forces. The required thickness can be determined based on structural analysis and design codes.
