This video is part of a series on the behavior of a ductile, singly reinforced concrete beam subject to loading. It provides you with an overview of how RC beam behaves under load and describes the stages that are important for analysis and design.
Part 1: Describes RC beam behavior under load in terms of the moment-curvature diagram. Identifies the stages of beam behavior that are relevant for analysis and design of RC beams.
Part 2: A closer look at stage 1: the uncracked-elastic RC section
Part 3: A closer look at stage 2: the instant concrete cracks in tenstion
Part 4: A closer look at stage 3: the cracked-elastic RC section
Part 5: A closer look at stage 4: ultimate, where concrete ruptures in compression
