Analysis and Design of Folded Plates

Abstract

This work presents the preliminary analysis of folded plates using three procedures .First one is Transverse slab analysis, longitudinal beam analysis and making compatibility of stresses. By using Winter-Pei method with correction analysis and without correction analysis and also design of reinforcement in folded plates and supporting diaphragms. This work also presents ananalysis of continuous folded plate roofs considering the effects of relative joint displacements. For this analysis the normal modes of the lateral beam vibration were used as the form of the deflection curve and the loading was sinusoidal. By using symmetry and anti-symmetry, a possible method of analyzing prismatic folded plate roofs comprising one bay transversely but continuous over two or more spans longitudinally is suggested.
