Abstract
This paper is concerned with the determination of effective widths of the flanges of prestressed single T-beams. There does not appear to exist any authoritative opinion on the effect of prestressing on shear lag when dealing with a monolithically constructed T-beam. Existing results can probably deal with the case when an already prestressed rib interacts with a concrete slab through embedded dowels connecting the two. Results show that effective width values for the prestressed T-section under live load are slightly different from those for the unprestressed section. It is thought that the differences are such that a single table of effective widths could still be applied in both cases. Detailed results are presented. These results have been calculated for a uniformly distributed load and for point loading.
