BEHAVIOR ANALYSIS OF STAYED BRIDGE WITH DIFFERENT CABLE ARRANGEMENT USING STAAD PRO

This work will deal with the design and analysis for different cables arrangement with the different shapes of pylon using STAAD Pro. There are many types of cable arrangements among these we chose fan type, radial type, star type and harp type arrangements.  The pylons are of two laterals of stays i.e. “A” shape, “Y” shape, “H” shape and one axial layer of stays i.e. circular shape pylon. All the considered shapes of pylon have cross sectional area but are of circular shape.The most efficient arrangement will be proposed after analysis among these configurations. The comparison is made for shear force, bending moment, displacements for all the cases. The conclusion will make in respect to the efficiency of one of the arrangements. This can be useful in the modifying the drawbacks of others. This work will give directions to make other arrangements more efficient.Finally, among all these the circular H shape with harp and the fan shape configuration is the best configuration.
