LRFD for Composite Beams with Unreinforced Web Openings
Publication: Journal of Structural Engineering
Volume 114, Issue 3
Abstract
Design procedures are presented for composite beams with unreinforced web openings. The procedures apply to beams with either solid or ribbed slabs. Ribs may be either parallel or perpendicular to the steel member. Strength predictions are compared with test results and predictions of other analysis and design methods. Unique features include a general formulation for pure shear strength and a direct solution for strength under combined bending and shear. The procedures are easier to use than both detailed strength models and existing design techniques. Accuracy compares favorably with strength models and is superior to existing design techniques. A resistance factor of 0.85 is recommended for both shear and bending.
