Three full-scale pretensiond folded plater roof units were tested to collapse. One unit was made of normal structural concrete with straight prestressing strands, the second was of lightweight concrete with draped strands, and the third was also of lightweight concrete with draped strands. The test-loading in the case of the third unit was arranged to simulate, in addition to normal uniform loading, a IO-ton crane load near one support. The moduli of elasticity were obtained from the deflection under load. Ultimate moment, lateral stability of the free compression edges, diagonal tension, and punching-shear effects were observed. The theoretical analysis is not presented although the results of a theoretical analysis are given.
