Abstract
This paper presents a study of a typical 1·1 km bridge in the north of Italy against a background of new infrastructure development. The bridge is composed of five network steel arches. The design solution represents a lightweight alternative if compared to traditional arch bridges. Every network arch spans 130 m, is 17 m wide and has a maximum height of 25·5 m. The deck is a steel–concrete composite section resting on precast slabs. Hangers have a variable inclination according to the geometric optimisation analysis performed. Before the final structural design, parametric studies were developed in order to optimise the material grade, the structural shape and the structural detailing.
