With advancements in orthotropic deck sections design, these bridges gain wide attention of structure designers. Though as number of cables increases in cable stayed bridge, the redundancy of the structure increases and it becomes difficult to analyze the bridge structure. CSi Bridge are Midas Civil are most popular software package for analyses and design of cable stayed bridges.

Suspension Bridges
