Steel Framing

Steel Framing: Strength, Span, and Ductility

Structural steel is the backbone of modern commercial construction. Its exceptional strength-to-weight ratio allows for long clear spans and tall structures that would be impractical in other materials. But perhaps steel’s most important structural quality is its ductility: the ability to deform significantly before failure, making it one of the most seismic-resistant structural systems available.

Steel moment frames, braced frames, and shear walls can be configured to resist lateral forces from wind and earthquakes with precision and reliability. The material’s consistency (manufactured under strict quality controls) means engineers can rely on its properties with high confidence.

Common Steel Systems

• Moment frames: Resist lateral loads through rigid beam-column connections (ideal for open floor plans)
• Concentrically braced frames: Diagonal braces carry lateral loads efficiently in high-seismic zones
• Eccentrically braced frames: Combine ductility with stiffness for optimal seismic performance
• Steel deck and composite systems: Lightweight, fast-to-construct floor systems for multi-story buildings
