Abstract:
`The results of load tests on four prestressed concrete multi-girder bridge decks are presented. The girders have been used to form both tee and pseudo box decks each of which has its own distribution characteristics. The measured distribution of beam soffit stresses are compared with predictions using a grillage analysis. For the beam construction good correlation was obtained but for the pseudo box deck measured stresses were less than those predicted. In the latter case good correlation was obtained by substantially increasing the torsional stiffness of the transverse grillage members.
