Deflection of Reinforced Concrete Beams - Example using ACI 318-19

This video presents an example problem for calculating the immediate live load deflections of a reinforced concrete beam according to ACI 318-19. The effective moment of inertia for the beam, which has changed in the most recent version of the code, is computed for dead only and dead + live loading. The service-load displacements are computed, and then the appropriate ACI 318-19 deflection limit is checked.
