New punching shear reinforcement - Shearband

This new punching shear reinforcement system developed in the UK, has led to several International patents.

The new shear reinforcement system, called the Shearband, differs from all existing systems because:
- It has a small thickness and can be placed on top of all other reinforcements, with minimal loss of cover. This has huge benefits such as an increase of the effective depth of flexural reinforcement, the simple and efficient placement of reinforcement, the ability to anchor to all the upper layers of reinforcement, or all the bottom reinforcement when necessary, and it acts over the entire concrete core.
- It is an adaptable system that can accommodate greater tolerances in placement, and simply and uniquely enables the quick addition of extra reinforcement where required.

In addition:
- It can be designed by using the existing design codes.
- It can be used in addition to other systems.
- It is light, requiring only man-handling.
- It is easy to store on or off site.
- It can allow for the design of thinner slabs with all the added benefits.
- All the reinforcement placed is useful.
- There is no undesirable increase in the slab's flexural capacity.
