| description | Abstract Due to extreme business competitions in bridge construction industries, the cost reduction became the most important issue in winning a contract bidding. The largest bridge construction cost saving can be obtained by using precasted construction method and by reducing required number of girders, columns, and decks in the bridge system. Therefore, an precasted arch deck system is proposed to widen the lateral span of the deck, which can result in reducing the number of required I-type PSC girders for construction cost saving. A usual lateral width of a flat deck is 1.5–2.0 m, but the width of arch deck is 2.5 m, an increase of 25–60%. Therefore, for a PSC girder bridge with a total width 10 m, a number of required girders needed for ordinary flat RC deck and arch deck is 5 and 4, respectively. This means that one less girder can be required, which means that 20% of girder construction cost can be achieved by using arch deck over ordinary flat deck. In this study, precasted RC arch deck is developed and manufactured to evaluate structural performance of the deck. The study results showed that arch deck has performance exceeding ordinary flat deck and can be used as alternative decks for precasted PSC I-girder bridge construction. The study results are discussed in detail in the paper. |
