I. INTRODUCTION ECENTLY, with the remarkable development in the use of cable bridges with large spans, wind effects become more paramount. Hence, the analysis of wind induced buffeting of large span bridges is considered necessary and cannot be disregarded. The stochastic vibration theory based on frequency domain encounter several complications in nonlinear wind induced structural response,
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
The key objective of the present work is to study the parameters affecting the static behavior of convex cable roof beams with central and edge rings, taking into consideration the nonlinear behavior to propose an appropriate approach for their preliminary calculations and design aspects. In such roofs, the cables are commonly suspended radially and attached at the perimeter of the roof to an elastically deformable compression edge ring and at the center to tension steel rings. A structure with
