Design of Composite Beams with Large Web Openings

Composite floor beams are a preferred solution for multi-storey construction this type of construction can achieve long spans and openings in the web of the steel section facilitating service integration within the structural zone. However the presence of large opening in the web raises additional design considerations.

This new design guide provides comprehensive coverage of the design of a full range of fabricated and rolled beams with isolated and regularly spaced circular or rectangular web openings. The guide also covers the design of asymmetric steel sections, elongated round openings, stiffened openings and notched beams.

Design guidance has been prepared in a way that compliments design to the Eurocodes and includes a full numerical worked example for a secondary beam with pairs of rectangular and circular openings illustrating the use of the guidance.
