Member strength checks (Composite beams: BS 5950)
Member strength checks are performed at the point of maximum moment, the point of maximum shear, the position of application of each point load, and at each side of a web opening as well as all other points of interest along the beam.
Shear capacity
Shear capacity is determined in accordance with clause 4.2.3. Where the applied shear force exceeds 60% of the capacity of the section, the high shear condition applies to the bending moment capacity checks (see below).
Bending moment capacity
This is calculated to clause 4.2.5.2 (low shear at point) or clause 4.2.5.3 (high shear at point) for plastic, compact and semi-compact sections.
