Course Description:
CE473  Steel Structures
(Required for a BSCE degree)
Introduction to types of steel, advantages of steel structures and the concept of LRFD approach. Strength and design of tension members, bolted and welded connections. Analysis and design of roof trusses. Strength and design of columns, beams and beam-columns. Analysis and design of frame structures. As well as design of bolted and welded connection, splices, and column base plate. All designs are according to the LRFD – AISC specifications. 3 (3,1,0)

Class/ tutorial  Schedule Class is held three times per week in 50-minute lecture sessions. There is also a 50-minute weekly tutorial associated with this course.
Computer Applications Computer spreadsheets are encouraged for developing design aids and carrying out systematic steps of design. Commercial and educational structural steel design software can be used during the course.
Projects A project of analyzing and designing a typical steel industrial structure is offered for students during the course.
Contribution of Course to Meeting the Professional Component
  1. Students use latest codes, design manual for designing structural systems within appropriate constraints including satisfying design criteria.
  2. Students recognize the role of professional societies in developing codes and standards and updating current knowledge.
Relationship of Course to Student Outcomes
  1. Students apply algebra, elementary calculus, and principles of mechanics.
  2. Students design structural systems and recognize the interaction with non-structural components
  3. Students recognize their role with an engineering team carrying other aspects of design and the interaction of decisions made by various architectural and engineering teams.
  4. Students are encouraged to consider alternative systems and parameters to achieve the project goals.
  5. Students recognize the ethical and professional responsibility in achieving safe and economical design, and the impact of their design on the well-being of the society.
  6. Students develop the background to communicate effectively because the course stresses fundamental principles behind code provisions.
  7. Students recognize the need for technical updating on a continuing basis because the course stresses the changing nature of technology, materials, codes and specifications.
  8. Students recognize the importance of reading and understanding technical contents in English in order to achieve life–long learning and be able to carry out their responsibilities.
  9. Students recognize the important role of computers in facilitating analysis and design of structural members and systems.
