Abstract:In view of the difficult problems of complex cable adjustment in landscape cable-stayed bridge, taking a spatial twisted pylon cable-stayed bridge as an example, a practical method of cable force optimization is proposed. The method can realize the intuitive and adjustable multi-objective cable force optimization, which is not limited by the program and can quickly determine the reasonable cable force. The method can also realize the subjective controllability of the designers, and help the designers quickly grasp the structure association characteristics while adjusting the cables.
