Abstract:
Information on the shape of the yield criterion for isotropic reinforced concrete slabs under biaxial moments is obtained from experiments on model rhomboid slabs. The results support Johansen’s proposed square criterion, and also the hypothesis that kinking of steel across cracks is not significant. A method is developed for predicting the main features of the moment-curvature curves for slabs under a given combination of bending moments, from the properties of the steel and the concrete.
