Three Pedestrian Steel Bridges in Spain

Pedestrian bridges with small to medium spans open up the possibility to explore new forms, new materials and construction methods.

Three case studies of urban road and pedestrian Spanish bridges are presented in this paper:

• Vallparadis pedestrian bridge is a three 33-m span spatial steel truss of hollow tubes, a very slender and light structure, with a composite concrete-steel deck supported by a parabolic bottom chord and lateral ribs below deck level and at an inclined angle to vertical (completed in 2007).
• Matadepera pedestrian bridge is a very slender steel box girder with a length of 53 m (completed in 2007).
• Zumaia pedestrian bridge is a hybrid structure combining stainless steel and GFRP profiles and planks. The bridge is under construction.

The paper will focus on following aspects: conceptual design, structural behaviour and construction.
