Experimental investigation of the shear capacity of plastic hinges
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.
