How to determine the Nominal Flexure Capacity of a Singly Reinforced Concrete Beam

In this video I go over how to determine the nominal flexure (moment) capacity of a singly reinforced rectangular concrete beam per ACI 318-14 in 5 steps. Steps include calculating the effective depth d, setting up strain and stress compatibility, equilibrium and obtaining the nominal flexure (moment) capacity of the beam section. A final step is included to ensure reinforcement in the concrete section meets minimum area of steel requirements. TIMESTAMPS Step 1 - Set up Strain and Stress Compatibility Step 2 - Determine depth of concrete compressive stress block Step 3 - Confirm steel reinforcement has yield (Ensures ductile failure) Step 4 - Calculate the nominal flexure (moment) capacity Step 5 - Confirm compliance with minimum area of steel requirements Interested in obtaining a PDF version of the calculations?
