Abstract
In the present paper creep analysis and torsional vibration analysis of cable-stayed bridges with two edge composite girders are discussed. For this type of the bridges there occurs stress redistribution not only within the composite girder but also between the girder, the cables and the pylons due to creep of concrete slab. Two creep analysis methods are presented, applied to an assumed bridge and compared.
To conduct torsional vibration analysis precisely is very important for this type of bridges with regard to aerodynamic stability because of relatively low natural frequency caused by low torsionaly rigidity of the open girder section. Also two analysis methods are presented, applied to the bridge and discussed.
