ANALYSIS of PYLON CABLE STAYED BRIDGE due to WIND LOAD
A typical cable stayed bridge is a continuous girder with one or more towers erected above piers in the middle of the span. Cables allow a slender and lighter structure which is still able to span great distances. For longer span cable-stayed bridges, careful studies must be made to guarantee the stability of the cables and the bridge in the wind. In this paper, a cable stayed bridge with high pylon reinforced concrete is analized due to wind load. The wind load is based on UBC 1997 and AS/NZS 1170.2:2002 regulations. The numerical analysis is conducted using SAP 2000. The results show that the displacements are significantly difference for the high wind speed between the UBC 1997 and AS/NZS 1170.2:2002 regulations.
