| Abstract: | Adopting the structure of continuous
rigid frame in construction of large-span beam bridge is an inevitable developing trend.
The measures for decreasing temperature stress and protecting piers from vessel impacting
are described. The data from some of domestic and overseas large-span beam bridges with
continuous rigid frame structure are given and analyzed. The superstruture-lightening and
non-drop-construction for closing-up of side span are discussed in the paper. |
