Kábelhídok

Kábelhídok, also known as cable-stayed bridges, are a type of bridge in which one or more towers, or pylons, support the bridge deck from which cables run diagonally to the deck. These cables are typically made of steel and are anchored to the towers and the deck. The tension in the cables distributes the weight of the bridge deck, allowing for longer spans than are possible with simply supported beams.

The design of a cable-stayed bridge involves a careful balance of forces. The pylons bear the primary load, transferring it to the foundations through compression. The cables, under tension, pull upwards on the deck, counteracting the downward forces of gravity. This system of pre-stressed elements allows for a very efficient and elegant structural solution.

Cable-stayed bridges can be constructed with one or more pylons, and the arrangement of the cables can vary. Common configurations include a fan shape, where the cables all originate from the top of the pylon, or a harp shape, where the cables run parallel to each other. The choice of configuration depends on factors such as the span length, desired aesthetics, and site conditions.

These bridges are known for their distinctive modern appearance and their ability to span significant distances, often across rivers, valleys, or busy shipping lanes. They require precise engineering and construction techniques to ensure stability and longevity. The development of cable-stayed bridge technology has made them a popular choice for major infrastructure projects worldwide.
