Landquart Bridge Dalvazza

The Dalvazza Bridge is a so-called Vierendell girder construction in reinforced concrete. The inventor of this system is the Belgian engineer Arthur Vierendeel (1852-1940). This support system consists of upper and lower belts, between which vertical posts are inserted. The diagonals usually used in half-timbered houses are missing. The characteristic interplay of the similarly strong posts and straps is an essential feature of all Vierendeel beams. It has an archaizing effect that is directly moving. Certainly, this strong aesthetic appeal is an essential moment in the spread of this system, which is technically quite controversial because of its elaborate knot formations. In Belgium, numerous bridges with Vierendeel girders have been built; in Switzerland, the Dalvazza Bridge is probably the only example.
