SPLICED SEGMENTAL PRECAST CONCRETE BRIDGES USING STAGED POST-TENSIONING

Precast concrete i-girder sections are widely used in bridge construction in British Columbia. A good deal of attention has been paid to methods of splicing girder segments to achieve structural continuity or to extend the span range to which the girders can be applied. A promising development has been the hybrid girder design, whereby pretensioned i-girders are spliced and post-tensioned in the field to achieve continuity. The same technique can be used for precast box-girders which are especially suited to bridges where plan curvature is involved. Four examples of recent bridges using this technique are reviewed, while the limitations and scope for future development are discussed. (Author/TRRL)
