20. BRACED ROLLED STEEL BEAMS

The chapter focuses on the behavior and design of laterally supported steel beams according to LRFD provisions. It emphasizes the methods to select efficient beam sections for bending moments, determines flexural strengths, and discusses failure modes and classifications of steel beams. The chapter further outlines the nominal strength requirements and flexural design principles, including considerations for different types of beam cross-sections.
