| Abstract | Tests on square bonded post-tensioned bridge slabs were carried out. Five prestressed slabs were tested to destruction to investigate the effect of transverse prestress on the strength of the slab. The bridge slab was a one-sixth scale model of a 30 ft square bridge to accommodate two American Association of Highway Officials' H20-S16 vehicles. The thickness of the slab was 1 1/2 inches. Longitudinal prestress was kept constant; π, the percentage of transverse to longitudinal prestress, was varied in the range 0–100%. The results of loading tests are analysed. Increase in transverse prestress improves the load-deflection characteristics of the slabs. There is improvement in the cracking load up to π = 33%, and beyond this the cracking load is constant. The ultimate load capacity shows improvement up to π = 33%, but beyond this figure the load-carrying capacity appears to be the same for all slabs. |
