Abstract
This paper discusses an analysis of the shearing forces around the drop panel of a flat slab structure. In this study, several shapes of the drop panel are investigated in case of an uniformly distributed load. The analytical solutions of the shearing forces are derived from the analogy between the equation of a slope of the membrane and the equation of a shearing forces of a plate. The results of the shearing forces among the several shapes are obtained by the experiments in membrane.
