Increasing the maximum span length for cable-stayed bridges has been always a
challenging target. To overcome resections on maximum span length associated with
the classical systems, a modified statical system should be considered. In this paper, a
comparative analysis for a modified statical system is presented. The classical vertical
pylons are replaced by pairs of inclined pylon legs (V-shaped) spreading out
longitudinally and connected at the top by horizontal ties. Two different V-shaped
systems are investigated. The effects of different cables configurations and numbers are
considered. The results .ale compared with a classical fan-type cable-
stayed bridge system, The numerical results indicate the feasibility of longer spans,
since the modified statical system gives much less responses than the classical system. |
