摘要
The girder and cables may be made of high strength steel and the girder is of metal sheeting which is elastically deformed into an upward-curving concave shape. The metal sheets are inserted in pairs into a wire-stretcher and are pre-stressed into a shape maintained by triangular tie-rods placed on. The girder may contain two bottom cables of different shape, and the additional cables improve the girder load bearing capacity and reduce deformation.
