The mechanisms for resisting flexure and shear in the plastic hinge zones of beams, which are subjected to cyclic loading, are examined. The results of thirty-eight beam tests which have been reported in the literature are reviewed, and criteria are developed
for predicting the energy which may be dissipated and the accumulated inelastic deformation that may be sustained before strength degradation occurs.
