The influence of plastic strains in the longitudinal reinforcement in presence of high shear forces in beams and slabs without stirrups was investigated performing a series of tests of eight ordinary reinforced concrete beams 8.4 meters long with 0.79% reinforcement ratio. The tests show that the shear capacity of plastic hinges decreases with increasing rotation. The article presents a description of the tests along with the main preliminary results.
