Course Objective

To introduce students to the general behavior and design of steel members. The student is expected to compute member loads and design members to resist them. All course work is based on the latest edition of the AISC Manual of Steel Construction. Design and analysis of beams, tension members, columns, base plates, bearing plates, and connections are covered. The integration of individual members into the overall structure is stressed throughout the semester. Strength, deflection, and durability are also covered.

Instructional Methods

Classes will be lecture based with example problems, readings may be assigned.

Grading

The course is divided into modules for which students must demonstrate competency with tests.

Attendance

Attendance will be taken at every class session. All students who are absent from class twice without an excuse will receive a written warning. Should a student miss the third class the student will be notified writing that they must withdraw from the class or fail, as any additional participation will not be acknowledged.
