The calculation of the cable forces is a distinctive aspect of cable-stayed bridges design when compared to other types of bridges.ġ The development of methods of structural analysis of highly statically indeterminate structures and application of electronic computers. Special attention on aspects other than mathematical calculations should be given. Spine model uses frame object whereas Area object model uses area object with preferred maximum submesh size of 1 m for modelling. Ease of construction was a primary concern to enable municipal or county work crews to erect the bridge and reduce the overall cost of the structure. Brief Description of Cable Stayed Bridges Cable stayed bridges are indeterminate structures. Preliminary Design of Cable-Stayed Bridges In general the height of a pylon in a cable-stayed bridge is about 16 to 18 the main span. The main element of a cable suspended bridge is the cable system. Superstructures the bridge is designed as a cable-stayed beam with two spans 140560700 m The superstructure of the bridge consist of. Cables stretch diagonally between these pillars or towers and the beam. For the sake of comparison the cost design of the considered cable-stayed bridge is. Stiffening girder tower and inclined cables.Ĭables are the most important elements of a cable-stayed bridge. The structural system consists of three main structural sub-systems. The cables in a cable-stayed bridge are all inclined Figure 1910.

For cable-stayed bridges the cable forces are an important factor in the design process 4. Depth of stayed girder ranges from 160 to 180 the main span and is usually 8 to 14 ft averaging 11 ft.
