| 摘要 |
The present invention relates to an ultra high strength fiber reinforced concrete segmental box girder and a construction method thereof, which improve the durability of a box girder having a span of about 50 m, ease of mounting, and construction performance as the fiber reinforced concrete segmental box girder maintains a weight, which is a half of the weight of a conventional concrete box girder, and a girder depth, which is 2/3 of the girder depth of a conventional concrete box girder, by mixing 2-4% of steel fiber or plastic fiber compared to the volume of ultra high strength concrete; improve easy of mounting and construction performance by reducing the weight compared with the conventional box girder; and improve cost efficiency by reducing construction costs through the design load reduction of a lower structure. |
