7.41. Steel Design (Mandatory)

7.41.1. Justification ↑ Back to top

Steel Design covers the fundamentals and application of the limit states design method (LRFD/ASD) to structural steel members and connections. The course addresses structural steel grades, design criteria and load combinations, the design of tension and compression members, compact and non-compact beams and plate girders, beam-columns under combined flexure-compression/tension, bolted and welded connections, and composite members in compression and in flexure. It provides the design competencies required for steel-framed buildings and industrial structures.

7.41.2. Generales Goals ↑ Back to top

1. Apply LRFD/ASD design criteria and load combinations to structural steel members.
2. Design tension members, compression members, beams, and plate girders using the limit states method.
3. Design beam-columns under combined axial force and bending, and their bolted and welded connections.
4. Design composite members in compression (encased and concrete-filled columns) and in flexure (composite beams).
