Shear strength of reinforced concrete plastic hinges
subjected to seismic action

ABSTRACT: The shear strength of reinforced concrete beams is reduced by axial elongation of the plastic
hinge regions during cyclic loading. In members with shear reinforcement this elongation may also affect the path
of the shear cracks and the inclination of the compressive stress field. Thus, the effective concrete compressive
strength decreases and/or the contribution of the concrete to the shear ...
