Static Analysis of Equal Two Span Cable Stayed Bridges with Various Shapes of Pylons

Abstract

Now with new world view, the field of cable stayed bridges become very important. This paper is concerned about the study of two spans cable stayed bridges with various shapes of pylon. Three types of these bridges as fan, harp and radiating shapes are considered. The static analysis is carried out for mathematical models with double plane of cables considering the parameters affecting the response. These parameters include: the variations of pylon shape, the variation of the height of the pylon to span of the bridge, different connections between pylons and floor beams, the arrangements of cables, initial tension of cables, and different cases of loading for floor beams. The analysis is done by a FORTRAN program based on the minimization of
