Specification for Structural Steel Beams with Web Openings (25-97)

This specification covers the design of composite and noncomposite beams with web openings. Basic design procedures involve determination of maximum nominal flexural capacity, maximum nominal shear capacity, and interaction of flexure and shear. Section properties are limited to ensure ductile behavior. Rectangular and circular openings, with or without opening reinforcement, are addressed. The specification follows load and resistance factor design philosophy.
