Strength during construction - I3.1c (360-05), I3.1b (360-10, 360-16 and 360-22) (Composite beams: AISC 360)

Flexure

Checks are performed at the point of maximum moment along the beam based upon the properties of the steel section alone in accordance with Section F2.

Lateral torsional buckling checks

When the forms are attached to the top flange then full lateral restraint can be assumed, irrespective of the angle of the deck. In this case you should indicate the beam is continuously braced.

In other cases any incoming beams will be automatically identified.

Each sub-length which is not defined as being continuously braced is checked in accordance with Section F2.
