faculty-legacy.arch.tamu.eduFor beams, the concrete only works in compression over a rectangular “stress” block above the n.a. from elastic calculation, and the steel is exposed and reaches the yield stress, F y For stress analysis in reinforced concrete beams the steel is transformed to concrete any concrete in tension is assumed to be cracked and
