CE 523 Theory and Behavior of Steel Structures

3 Credit Hours

Bolted and welded connections subjected to eccentric shear and combined bending and shear; framed beam connections; fully restrained moment connections; beams subjected to torsion and combined bending and torsion; flexural, torsional, and flexural-torsional buckling of compression members; members subjected to combined bending and axial compression.


CE 426 Structural Steel Design or an equivalent undergraduate course in structural steel design. Working knowledge of AISC design requirements for rolled steel shapes subjected to tension, compression, and flexure is required. In addition, familiarity with basic connection design including bolts and fillet welds subjected to shear is required. CE 523 CANNOT be your first course in steel design.

Permission of the instructor is required to register for CE 523. Registration will be allowed upon satisfactory review of the attached survey which must be completed and emailed to

The first homework assignment will contain a set of review problems from undergraduate steel design

Course Objectives

By the end of the course, you will be able to analyze and design:

  1. bolted and welded connections subjected to eccentric shear and to combined bending (tension) and shear,
  2. framed beam connections (simple shear connections),
  3. continuous beam-to-column connections (moment connections),
  4. laterally supported beams subjected to combined bending and torsion,
  5. laterally unsupported beams subject to lateral-torsional buckling,
  6. compression members considering flexural, torsional, and flexural-torsional buckling, and
  7. members subjected to combined bending and axial compression (beam-columns).

Course Requirements

HOMEWORK: 30% (Note that a homework assignment will be due the last week of class.)

PROCTORED EXAMINATIONS: Two, 75 minute (in-class) tests, 30%
