Happy Wednesday, The last 2 weeks, you got an introduction to what the moment of inertia and section modulus are and how you calculate them for “easy” and common cross-sections. BUT, we didn’t cover one of the most used cross-sections in structural engineering, the reinforced concrete cross-section, which is a composite section. So, today, we’ll cover how you calculate the moment of inertia of uncracked reinforced concrete sections, because you need that when you calculate a reinforced...
