| Abstract | Five prestressed concrete right bridge slabs have been tested to destruction to investigate the effects of variation of transverse prestress on the strength of the slab. The slabs tested were one¬ sixth scale models of a 30 ft. square bridge to accommodate two American Association of Highway Officials’ H-2O-S-16-44 vehicles. The thickness of the slab was 1)4 inches while the span and the width were each equal to 5 feet. Longitudinal prestress was kept constant in all slabs, while the transverse pretress was varied in the ratios of 0,1/J,1/2,2/3 and full value of longitudinal pre¬ stress. Results have shown that in the elastic range no additional effect is obtained by increasing transverse prestress beyond one third of the longitudinal prestress5 but, in the inelastic range, the increase in the transverse prestress increases the transverse stiffness, which not only affects the deflection of the slab, but increases the load-carrying capacity of the slab. However, there is a limiting value of transverse prestress beyond which any in¬ crease does not affect the ultimate load. |
