+ Shear Reinforcing Elements

Simple, fast and safe - perfectly suited for members subject to shear stresses

Shear reinforcing elements QE are used as shear reinforcement to increase the shear resistance of slabs and walls. With the positioning of the elements between the reinforcement layers, installation is particularly simple and quick.

Shear reinforcing element QE

Application

Shear reinforcing element QE

Composition

Shear elements QE are U-shaped mesh-like or ladder-like reinforcing elements, which are industrially produced by electric resistance welding similar to the production of reinforcing wire fabrics. The wire used for both the chords and the vertical bars is reinforcing steel B500A according to ÖNORM B 4707. Shear elements QE are especially suited as shear reinforcement at the support of floor slabs resting on walls or beams and as shear reinforcement of foundation slabs.

Types

Shear elements QE come in heights from 100 mm to 600 mm.

The most commonly used types are available in stock.

QE-Types marked with * are available on request.

1) Width of elements refers to the centre distance of vertical bars in cross direction.

2) The required amount of shear reinforcement SW,erf (e.g. based on a FEM calculation in accordance with ÖNORM EN 1992-1-1 with fyk = 500 N/mm2) has to be increased by the factor 1,0/0,9. Ved must not exceed 0,45 x VRd,max. The angle θ between the concrete compression struts and the beam axis perpendicular to the shear force is limited by 1,0 ≤ cotθ ≤ 1,7.
