Versatile Coverage of Steel Design Topics

The book doesn’t stop at basic beam or column design. It includes specialized chapters on:

  • Plate girders – ideal for long-span bridge and industrial applications

  • Composite beams – combining steel and concrete for efficient floor systems

  • Bolted and welded connections – analyzing how loads transfer through joints

  • Lateral bracing and stability issues – key concerns in modern steel construction

This depth makes it a reliable reference not just for education, but for actual project work.

User-Friendly Layout

Designs can get complicated. That’s why the book uses:

  • Clean diagrams

  • Summary tables

  • Flowcharts for decision-making

  • Appendices with properties, formulas, and standard sections

Whether you’re reviewing beam buckling equations or selecting a steel shape, you can find what you need quickly.
