Analysis of Composite Beams with Web Openings
Publication: Journal of Structural Engineering
Volume 110, Issue 9
Abstract
The ultimate strength is derived for a composite beam comprising a ribbed slab and steel section with a large rectangular web opening. Shearing force is assumed to be carried in both the steel section and the slab at the opening, and the method accounts for partial shear connection. Good agreement is demonstrated with maximum loads measured in tests. Comparison with a more detailed theory presented elsewhere shows good agreement over the full range of moment‐to‐shear ratio. Caution is recommended when applying the theory to cases differing substantially from the parameters of the test beams.
