| Abstract: |
The TrengTreng - KayKay Bridge is a cable-stayed bridge that crosses over the River Cautín and it is located on the outskirts of Temuco, Chile. The design of the pylon`s shape is based on a local legend and it represents two snakes, corresponding to good and evil, biting each other. The structure, with a total length of 240 m, is composed of four minor spans and the main one, 140 m long, is cable-stayed. The deck is 27 m wide and bears two traffic lanes, and its corresponding sidewalks, in each direction and a bike lane. Both the deck and the pylon are designed as prestressed concrete structures. The main staying system is composed of two planes of 12 cables each one, arranged creating a fan disposition. The back staying system is formed by two pairs of four parallel cables that are anchored two the retaining abutment. Once the erection is finished, TrengTreng – KayKay will be the first modern cable-stayed bridge in Chile. |
