Analysis of a Cable-Stayed Suspension Hybrid Bridge Considering Vehicular Loading using CSI Bridge

Abstract

Cable-stayed bridges are built for providing connectivity over obstacles such as rivers, mountains, flyovers over rotary squares and valleys for a long span. Cable stayed bridge provides ample stability and utilises structure material and further its advantages goes in for cheap maintenance and design. Design of the bridge is highly dependent on its function and purpose and the nature of terrain of the site.
A bridge type known as a suspension bridge has its deck suspended by vertical suspenders and suspension cables. The main structural elements of a suspension bridge system are stiffening girders/trusses, main suspension cables, main towers, and cable anchorages at each end of the bridge. Vertical suspenders sustain the weight of the deck and the traffic load, while the main cables are stretched between towers and eventually connect to the anchorage or the bridge itself. The superstructures of suspension bridges are constructed utilising the cable erection technique similarly to other cable-supported bridges.
