The general structural action of prismatic folded-plate roofs of simple span is considered without derivations or formulas. A numertcal example of a two-unit folded plate roof on a simple span of 56 ft is then analyzed for combined dead and live load by one of the approximate methods, taking account of the effect of plate deflections. The results are obtained in the form of transverse moments in the slab, longitudinal flexural stresses and principal tensile stresses in the plates, and shearing forces between the plates and their end supports. The values obtained for longitudinal flexural stresses at midspan and shearing forces at the sup-ports are compared with those given by the ordinary beam theory.
