ST7-1.40.60.3 Precast Girders with an In-Situ Cast Deck
Combining pre-cast and in-situ cast components in bridge design is complex. The bridge geometry is shown at right. The bridge span is angled and consists of two longitudinal steel girders with periodic internal reinforcement and a concrete deck.
The span is about 16.5 m and the deck width is 9 m.
The deck is constructed by first laying transverse pre-cast 80 mm thick transverse girders, then performing an in-situ cast on top of them.
The pre-cast concrete transverse girders do not contribute...
