7.40. Reinforced Concrete Design I (Mandatory)

7.40.1. Justification ↑ Back to top

Reinforced Concrete Design I introduces the principles and methodology for the design of reinforced concrete members following limit state design philosophy and the ACI 318 building code. Building on the mechanics of materials, students learn to design beams for flexure and shear, columns for combined axial load and biaxial bending, one-way slabs, and to verify deflection and serviceability requirements. The course also covers the design of supported and cantilevered concrete staircases and an introduction to shallow foundation design, providing the structural design foundation required for subsequent reinforced concrete and earthquake-resistant design courses.
