Summary:

    The course will cover following areas:

• Analysis and design of reinforced concrete beams and columns for flexure, shear, axial load, torsion, and anchorage, including compression theory and strut-and-tie models.
• Behavior and design of two-way slab using the direct design method, equivalent frame method, and strip method, including slab-column connections and beam-column connections.
• Behavior and design of reinforced concrete frame and frame-wall structures for gravity and lateral loads.

Course Workload:

• Readings (textbook, selected journal papers, additional handouts)
• 4 -6 Homework assignments (consisting of: textbook problems, MathCad, spreadsheets)
• One midterm (before Thanksgiving)
• 1 design project
• 1 Final exam (schedule and format to be determined)
