| Abstract: | Taizhou Bridge is the first three tower two span suspension bridge with spans over 1 000 m in the world. Its main spans are 2×1 080 m; the middle tower is a steel frame with longitudinal herringbone shape and lateral gate shape; the side towers are gate shaped concrete frames; the stiff girder consists of flat streamline steel box girders, with a total of 136 steel box girders of about 33 426 t for the whole bridge. This article determines the proper lifting sequence of steel box girders of this three tower suspension bridge by analyzing the effect of steel box girders lifting sequence on structural system and difficulty in construction . |
