Serviceability limit state - Crack proof

Tension of the reinforcement as percentage of fyk.

ENV 1992-1-1: Art. 4.4.2.2(39), Gl.(4.78)

Default value: 100% (fyk)

Maximal permissible crack width.

ENV 1992-1-1 Art. 4.4.2.1 (6), default value = 0.3 mm.

Maximal allowable crack width at the surface with positive / negative Z co-ordinate (in the local co-ordinate system of the plate).

Maximal allowable distance between reinforcement bars at the surface with positive / negative Z co-ordinate (in the local co-ordinate system of the plate).

Coefficient beta1 of the crack formula.

ENV 1992-1-1, Art. 4.4.2.4(2), Gl.(4.81)

Default value: Beta1=1.0

Coefficient k1 of the mean crack distance formula.

ENV 1992-1-1, Art. 4.4.2.4(2), Gl.(4.82)

Default value: k1=0.8

The user selects the type of load case that causes

the appearance of cracks. The load causing cracks

can be due to:

• prevailingly external load,

• internally imposed deformation,

• externally imposed deformation.

The effective utilisation of concrete in tension. It can reduce the strength of concrete in tension. If set to zero (default value), the coefficient is not taken into account.
