This paper proposes a concept of a beam prestressed by bending. An application through an example of footbridge with three supports is shown and illustrated. By bending a beam with a central cable, this cable will be in tension. This cable is then able to act as column which is an advantage as it cannot buckle. In this example, the method of calculation is given and shows that composite materials are well suited for this application. Finally the construction of a scale one model is shown and the authors conclude on the interest of such concept.
