Arrangement of Cable on Prestressed Cable-Beam Structure System

The article analyzes the prestressed concrete cable-beam structure system when it is on the condition of sigle span and sigle direction.The paper summaries the application of cale and presents the design ideas of cable,arranges reasonably the shape of cable,deduces the equation of cable when it is under the condition of curve,and gets the conclusion. The height of the middle bar decides the height of the cable-beam,so it limits the ratio of sag and span to make the reasonable design in the paper and to embody the superiority of prestressed concrete cable-beam structure system.
