Curved cable-stayed bridge, funicular deck, antifunicular deck, concentric load, axial loadAbstract
The aim of the following study is to optimize the layout of a curved bridge deck. The guideline proposed is intended to ensure that the entire board is free of vertical axis bending moments. Two mathematical approaches are developed for the directive, a discrete and a continuous. For both, positive and negative sign for the axial load in the deck is studied. To make the possible implementation easier, a least square approximation is made for both signs. Two examples will be developed to end the article.
