The purpose of this paper is to calculate shear stresses for the circular, elliptical and rectangular hollow slabs subjected to the shear force perpendicular to the axis of the holes, and to investigate stress concentration around the hole. Using that the hollow slabs are considered as continua of I-beams, in this paper the hollow slab is dealt as a cantilever of I-beam with a shear force applied at the end. Then stress function concerned with shear stresses satisfies two-dimensional Laplace equation. It is computed by B. E. M. As a result shear stresses are calculated. For application of the analogy between stress function and deflections of membrane, some experiments are practiced. Some interesting results about stress concentration for the hollow slabs are obtained.
