The cables should be additionally tensioned to counteract 50% of the combined temporary downward loads (live loads, wind, snow, ice, and earthquake). They are also more resistant to environmental changes (eartquake etc) because they can be flexible, where a concrete bridge will break. Any transportation option that needs a stiff platform cannot use a suspension bridge because of this fact. Cable-stayed bridges are a subcategory of suspended structures. In a suspension bridge, the main cable tension is concentrated in the anchorages at each end. Cable-stayed bridges differ from their suspension bridge in a way they don't require anchorages, nor do they need two towers. Suspension bridges have retained popularity around the world and this is evident with the number of these bridges in the United States. Suspension bridges need to be flexible enough to move with the wind, but not so flexible that they break. The compression in the deck-girder due to the horizontal components of cable stays forces is the cumulative sum of these components, approximately 55 to 65% of the total vertical loads on the main span depending on the span, the number of cables, and the height of cable connections at the tower. Cable stay is cheaper but difficult to build for long lengths, as you have to extend from the towers towards the middle without any support cable. The lower loads and shorter spans allow engineers to explore new approaches, transforming the building of these bridges into a testing lab for innovation.

The cables should be additionally tensioned to counteract 50% of the combined temporary downward loads (live loads, wind, snow, ice, and earthquake). They are also more resistant to environmental changes (eartquake etc) because they can be flexible, where a concrete bridge will break. Any transportation option that needs a stiff platform cannot use a suspension bridge because of this fact. Cable-stayed bridges are a subcategory of suspended structures. In a suspension bridge, the main cable tension is concentrated in the anchorages at each end. Cable-stayed bridges differ from their suspension bridge in a way they don't require anchorages, nor do they need two towers. Suspension bridges have retained popularity around the world and this is evident with the number of these bridges in the United States. Suspension bridges need to be flexible enough to move with the wind, but not so flexible that they break. The compression in the deck-girder due to the horizontal components of cable stays forces is the cumulative sum of these components, approximately 55 to 65% of the total vertical loads on the main span depending on the span, the number of cables, and the height of cable connections at the tower. Cable stay is cheaper but difficult to build for long lengths, as you have to extend from the towers towards the middle without any support cable. The lower loads and shorter spans allow engineers to explore new approaches, transforming the building of these bridges into a testing lab for innovation.
