Jul 22, 1997  A general framework aimed at dealing with the failure analysis of reinforced concrete beam-like structures is presented in this paper. It is based on the yield design theory combined with a “mixed modeling” of this kind of structure, according to which the concrete material is treated as a classical continuum, whereas the longitudinal reinforcements are regarded as elements working ...

A study of shear behavior of reinforced concrete deep beams

Reinforced concrete deep beams are vital structural members serving as load transferring elements. The behavior of reinforced concrete deep beams is complex. Nonlinear distribution of strain and stress must be considered. Prior to 1999, ACI 318 Codes included an empirical design equation for reinforced concrete deep beams.
