VIERENDEEL GIRDER PDF

The Vierendeel girder design is sometimes adopted in the design of footbridges. In traditional truss design, triangular shape of truss is normally used because the shape cannot be changed without altering the length of its members. By applying loads only to the joints of trusses, the members of truss are only subjected to a uniform tensile or compressive stress across their cross sections because their lines of action pass through a common hinged joint. Hence, bending, shear and axial capacity of these members contribute to the resistance to external loads. The use of this girder enables the footbridge to span larger distances and present an attractive outlook.

The use of this girder enables the footbridge to span larger distances and present an attractive outlook. However, it suffers from the drawback that the distribution of stresses is more complicated than normal truss structures.

Vierendeel bridge

A Vierendeel bridge is a bridge employing a Vierendeel truss , named after Arthur Vierendeel. Such trusses are made up of rectangular rather than triangular frames, as are common in bridges using pin—joints. Because of the lack of diagonal members, Vierendeel trusses employ moment joints to resist substantial bending forces. Owing to a lesser economy of materials and the difficulty of design before the advent of computers, this truss is rarely used in bridges outside Belgium. The form is more commonly employed in building structures where large shear walls or diagonal elements would interfere with the building's aesthetics or functionality. The first such bridge was built in steel at Avelgem , Belgium in , following development of the truss form and a method to calculate its strength in by Arthur Vierendeel. There are many more examples in Belgium, including some built in concrete, mostly designed by Vierendeel's many students from his long career as professor in civil engineering.
