Outline and Purpose of the Course	This course discusses manufacturing methods and mechanical characteristics of steel material used in steel frame construction, the make-up of framed construction, and outline of design methods; describes in detail the theory of plasticity, which determines collapse load, one of the main factors controlling the functionality and safety of steel frame construction; and explains structural design application methods. Also, appropriate exercises are assigned to teach students the theory.
Course Goals	Learn the theories needed to understand the mechanical properties of steel material and the mechanical behavior of steel frame structures, as well as design methods based thereon. In terms of the department’s learning/educational goals: B. Specialized knowledge and fundamental knowledge and B3. Ability to comprehend architectural structure.
