This document discusses the cracked transformed section method for analyzing reinforced concrete beams. It explains that when cracking occurs in the tension side of the beam, the concrete is no longer effective and the steel takes the tensile stresses. The effective cracked transformed section is used, where the depth is reduced by a factor k. Equations are provided to calculate k in terms of the steel ratio ρ. The depth and neutral axis location for the cracked transformed section model are then used to calculate the resisting moment capacity of the beam.
