Streamlined box girder type suspension bridge |
摘要 |
A streamlined box girder type suspension bridge comprises a plurality of towers for supporting the cables, and the center main span and side spans comprising streamlined box girders suspended by a plurality of hangers from the cables. An additional mass of an appropriate weight comprising the material which would not directly contribute to the strength of the box girder is formed as a core at the predetermined portion of the box girder in order to suppress the bending-torsional flutter arising from the streamlined shape of the box girder, and the core extends over the complete span of the bridge symmetrically and with respect to the longitudinal axis thereof.
