Summary
Tests on three prestressed concrete slabs of varying span/breadth ratios have given data concerning the load distribution properties of such structural forms.
The results for the distribution of deflexions and longitudinal and transverse bending moments under one, two and four equal loads are given and compared with results given by the theoretical analysis. The effect of considering Poisson's ratio in the theoretical analysis is discussed.
The distribution of the transverse bending moments, both in the transverse and longitudinal directions, is considered in detail. The maximum value of the transverse moment occurring under the Ministry of Transport abnormal load is esdmated and the position of the wheel loads to give the maximum moment is considered. The variation in the transverse moments along the span due to such abnormal loading is also discussed.
