Abstract
Considerable experimental research on the influence of shear on the performance of flexural hinges under reversed loadings has been reported in the literature. Using existing data, a means of making comparisons between test results is devised and design requirements for shear in members under reversed loading are suggested. Results of 65 tests from six investigations are compared on the basis of modified work index, a measure of the hysteresis exhibited by the test specimens under load reversals. Factors that significantly influenced the work index were level of axial force, shear span to depth ratio, and maximum applied shear stress. Design recommendations for maximum shear stress and minimum transverse reinforcement are developed for satisfactory performance of hinging regions.
