Punching Shear Reinforcement

Slab loads create shear stresses around columns, which, if they exceed the concrete’s shear capacity and insufficient reinforcement is provided, can cause punching shear failure, where the column punches through the slab. This stress is also transferred to the footing, potentially causing similar issues. Ancon Shearfix Punching Shear Reinforcement provides an effective solution by offering additional reinforcement around columns to mitigate punching shear risks in flat slab construction. The system consists of double-headed studs welded to flat rails, positioned based on design calculations or software-generated spacing. Suitable for all column shapes, Shearfix is easy to install with either top-down or bottom-up methods. It optimises head space, reduces building height, and offers significant time and material savings.
