     an experimental study on 18 simply supported ferrocement plates having a span/depth ratio of 2.0 was conducted. various wire mesh types were used as web reinforcement. flexural steel was designed to preclude failure in modes other than flexure. two groups, a and b, were tested under central uniform loads covering 10% and 67.5% of the clear span respectively. it was observed that, the percentage increase of shear capacity over the reference specimen is remarkable for group a and nearly equal to 40%. moreover, a hexagonal mesh, vf of 0.15%, improves the shear capacity than those of diamond and square meshes of 0.25% and 0.38% volume fraction respectively. specimens of group b demonstrate a slight increase of the ultimate shear capacity than those of group a despite that the web reinforcement is less effective as pointed out by comparing the results of each group with its associated reference specimen. a good agreement between the classical shear equations prediction and the experimental values is obtained for group a specimens whereas the ultimate shear capacity for group b is underestimated. it is also indicated that the strut and tie model is an inappropriate technique for the ferrocement plate design compared to the classical shear equations of deep beams.
