Cable-Stayed Bridge with S-Curved Girder: Shake Hands Bridge

A cable-stayed pedestrian bridge with an S-curved girder called Shake Hands Bridge is proposed. This type of bridge overturns the traditional notion of linearly constructed cable-stayed bridges. Cables support the S-curved girder from intersecting inclined towers creating a three-dimensional effect. The aesthetic design of the proposed bridge is examined using a model, a 3D computer-aided design diagram, a computer graphics diagram and a video. The proposed bridge is attractive and impressive, in harmony with the surrounding environment, and is considered to have great presence and to be an attraction in itself. From a structural point of view, it is found that the inclined tower has the effect of reducing the axial force of the girder and the tower itself and suppressing bending of the girder. On the other hand, it is found that the S-curved girder is more affected by torsion than a straight girder, but that there is no problem with safety. In addition, deflection of the girder due to live loading also satisfies the allowable value, there is no problem due to vertical or horizontal vibration, and the serviceability is sufficiently secure. Therefore, the proposed bridge is considered to be highly feasible.
