Construction Stage (Composite beams: AISC 360)
At construction stage the beam is acting alone before composite action is achieved and is unshored.
When you design or check a beam for construction stage loading the following checks are carried out in accordance with the relevant chapters of the AISC Specification, consistent with the approach (i.e. LRFD or ASD) used at the composite stage.
- Section classification (Composite beams: AISC 360)
- Shear strength during construction - I3.1b (360-05), I4.2 (360-10 and 360-16), I4.3 (360-22) (Composite beams: AISC 360)
- Strength during construction - I3.1c (360-05), I3.1b (360-10, 360-16 and 360-22) (Composite beams: AISC 360)
- Deflection checks (Composite beams: AISC 360)
