Distance between stirrups in multiple of diameters.

Distance between stirrups in mm.

Check of dimensions of the section.

Stirrups

• Maximum spacing: 25 times the diameter of bars.

• Minimum reinforcement ratio: 0.2%. Maximum thickness of the web for the calculation of the ratio: 400mm.

Webs thicker than 500mm will have multiple stirrups.

Condition for web thickness.

Transverse reinforcement of the slab (T-section).

Minimum reinforcement ratio: 0.2% in relation to the slab.

Check for minimal distance of bars during design and drawing.

Check for maximal distance of bars during design and drawing.

Minimum amount of transverse reinforcement, determined as a percentage of reinforcement in other reinforcement direction(s) at the same face. This control is active in ULS only, not in SLS!

SIA 262, Art. 5.5.3.2

Default value = 20%.

Minimum percentage oflongitudinal reinforcement, unconditionally.

Default value = 0%.

Walls and Shells:

If ON, the minimum pressure reinforcement (per cross-section) is calculated.

SIA 262, Art. 5.5.4.3

Default value = 0.6%.

Plates only:

Definition of the maximum percentage of reinforcement in the bending pressure zone related to the concrete pressure force

Compare with SIA 162, Art. 3.24.16

Default value = 50%.

If ON, the corresponding reinforcement is calculated automatically. The calculation is based on the requirement of the prevention of brittle fracture at the first crack appearance.

SIA 262, Art. 4.4.2.3.9, Tab. 16/1 und Art. 4.4.2.3.10, Fig. 31

Shells and Plates only:

Minimum percentage of tension reinforcement at the surface with positive Z co-ordinate (in the local co-ordinate system of the 2D member).

Default value = 0%.

Minimum percentage of tension reinforcement at the surface with negative Z co-ordinate (in the local co-ordinate system of the 2D member) or at each of the Wall faces, respectively.

Default value = 0%.

Maximum percentage of reinforcement any design point.

SIA 262, Art. 3.4.9.2 or 3.4.9.3, resp.

Default value = 8%.

Minimum percentage of shear reinforcement. The Norm does not stipulate any 2D shear minimum reinforcement!

Default value: 0%

Diminishing of the actual concrete strength of a stiffening 2D continuum due to parallel cracks (coefficient kc – per cent).

SIA 262, Art. 4.2.1.7

Default value = 80%.

Diminishing of the actual concrete strength of a stiffening 2D continuum due to general cracks (coefficient kc – per cent).

SIA 262, Art. 4.2.1.7

Default value = 60%.
