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