Kötelhidak

Kötelhidak, commonly known as cable-stayed bridges, are a type of modern bridge where the deck is supported by one or more towers, from which cables run directly to the deck. These cables, often made of steel, are tensioned and angled to carry the load of the bridge, eliminating the need for extensive piers or traditional suspension cables. The design allows for long spans, making them suitable for crossing wide rivers, valleys, or shipping channels.

The construction of a cable-stayed bridge involves anchoring the cables at regular intervals along the deck to the towers. The towers themselves can vary in design, from single pylons to A-shaped or H-shaped structures. The shape and placement of the cables, known as the cable plane, are crucial for distributing the weight and maintaining the bridge's stability. This system offers a degree of flexibility and resilience, allowing the bridge to adapt to wind and traffic loads.

The aesthetic appeal of cable-stayed bridges is also a significant factor in their popularity. Their elegant and often sculptural appearance has made them iconic landmarks in many cities. Early examples of cable-stayed designs can be traced back to the 17th century, but modern engineering advancements in materials and construction techniques have led to the development of the sophisticated structures seen today. Examples include the Millau Viaduct in France and the Sutong Bridge in China.
