Construction stage restraints​

These parameters define the lateral restraint condition of the steel beam during the construction stage, prior to composite action with the slab.

Top flange laterally restrained​

This condition represents cases where lateral movement of the top flange is prevented by temporary or permanent restraints present during construction.

Top flange is free to move laterally​

This condition represents unrestrained construction-stage behaviour, where no lateral restraint is provided to the top flange.

Web openings​

Web openings define penetrations within the web of the steel beam. The following parameters describe the geometry and position of each opening.

Type​

The type determines whether the opening is defined as circular or rectangular.

Width / diameter​

For rectangular openings, this parameter defines the opening width. For circular openings, this parameter defines the opening diameter.

Height​

Defines the vertical size of the web opening. This parameter applies to rectangular openings only.

Centroid from left of beam​

Defines the horizontal position of the web opening centroid, measured from the left end of the beam.

Centroid from top of beam​

Defines the vertical position of the web opening centroid, measured downwards from the top of the beam section.

Stud property​

This parameter references the stud definition used to represent the shear connection between the steel beam and the concrete slab.

Slab edge distance​

Defines the distance from the edge of the concrete slab to the centreline of the steel beam. This parameters applied only to edge beams.
