7.76. Reinforced Concrete Design II (Mandatory)

7.76.1. Justification ↑ Back to top

Reinforced Concrete Design II builds directly on Reinforced Concrete Design I, extending limit state design methodology to the structuring and design of building slab systems, seismic-resistant reinforced concrete structural walls (shear walls) and special moment frame provisions, and the use of structural analysis software for three-dimensional building modeling. The course also develops earth-retaining structure design, including basement walls, anchored walls, gravity walls, and cantilever and counterfort retaining walls, together with advanced shallow foundation design covering isolated, combined, connected, eccentric, and continuous footings. Through progressive, integrated design exercises, students apply current design codes to produce a complete seismic-resistant reinforced concrete building design, preparing them for advanced structural and earthquake-resistant design coursework.
