… up to 60 % Anchorage points in concrete are usually subjected to tensile as well as shear loads. The edge distances play a special role with shear loads. The goal of all planning is to introduce the highest possible forces into the concrete via the anchoring point. In all anchor solutions, the applied shear force is introduced into the concrete via the sleeve. Based on the load introduction position, the concrete prefers to break with a classic 60° concrete breakout cone. A new type of shear force anchor, the BT Q-Anchor, allows a very efficient utilisation of the concrete with experimentally determined load increases of up to 60 % due to its geometry.
