Pretensioned concrete double-T members are widely used as floors in parking garages. Uniformly distributed live load usually governs pretensioned design of the member in the main span direction, and the concentrated load usually governs the design of the overhanging outer flanges of the slab portion of the member. The article compares flange moments determined using elastic plate theory, various assumptions following the approaches given in the PCI Design Handbooks, yield-line theory, and consideration of the loadings suggested by Malik.
