DESIGN OF HORIZONTALLY CURVED WAFFLE SLAB STRUCTURES

Horizontally curved concrete slab structures are often used in bridge superstructures as well as in large auditoriums with a minimum number of supports. A method is developed to analyse and design such structur es based on their ultimate load-carrying capacity. The basis of this m ethod is the yield-line theory. The behaviour of prestressed versus re inforced concrete construction is examined. The analytical results are verified and substantiated by tests on horizontally curved waffle sla b models subjected to uniformly distributed and concentrated loads.
