| Abstract | An experimental program was made to determine the ultimate strength
of prestressed concrete slabs subjected to concentrated loads using
yield-line theory. Models of one rectangular and three square bridge
slabs, post-tensioned and grouted, were tested to destruction. The results
were incorporated with those of previous tests made in the SEATO Graduate
School of Engineering making a total of seventeen slabs tested. It was
verified that a logical prediction of the ’.ultimate load capacity of a
prestressed concrete slab can be made using idealized yield-line patterns,
provided that a reasonable assessment of ultimate moment of resistance is
made, and that the transverse prestress is at least 20% of the value in the
longitudinal direction. Suggestions are made as to the approach to use
for different types of prestressed concrete slab, i. e. bonded or unbonded,
over-reinforced or under-reinforced. Sample computations for each particular approach are illustrated. Experimental longitudinal load distribution
coefficients were determined. This was done in order to compare with the
theoretical distribution determined using orthotropic plate theory, which
was adopted in computing the elastic design loads.
