Beams

Min bar distance ds min

Min distance between reinforcement bars in a beam.

ČSN 73 1201-86, Art. 11.2.2.1

Default value = 20 mm.

Max bar distance

Max distance between reinforcement bars in a beam.

ČSN 73 1201-86, Art. 11.2.2.4, Table 19

Default value = 300 mm.

Max shear reinforcement distance

Maximal distance between links. The lower of the two input values is taken into account. The user may input the distance as a part of a cross-section effective depth or s/he may input the distance directly.

ČSN 73 1201-86, Art. 5.3.6

Default value = 0.75 and 400 mm, respectively.

Columns

Longitudinal reinforcement

Min bar distance ds min

Min distance between reinforcement bars in a column.

ČSN 73 1201-86, Art. 11.2.2.1

Default value = 30 mm.

Max bar distance

Max distance between reinforcement bars in a beam.

ČSN 73 1201-86, Art. 11.2.2.4, Table 19

Default value = 400 mm.

Shear reinforcement

Min bar diameter

Minimal link diameter determined as a maximum of the two input values.

ČSN 73 1201-86, Art. 11.6.6.2

Default value = 0.25 ds and 4 mm, respectively.

Max distance

Max distance of links in a column.

ČSN 73 1201-86, Art. 11.6.6.2

Default value = 250 mm.

Circular columns

Min number of bars

ČSN 73 1201-86, Art. 11.6.6.1

Default value = 6

Min bar diameter

ČSN 73 1201-86, Art. 11.6.6.1

Default value = 12 mm

Calculation of theoprac (columns and beams)

Test of min distance

If ON, the minimal distance between bars is checked during the design phase.

Test of max distance

If ON, the maximal distance between bars is checked during the design phase.
