Rein belt bridge
A bridle strap bridge , also called a false suspension bridge , is typically a suspension bridge in which the support cable is not in anchor blocks in the subsoilattached, but is connected to the deck girder. The horizontal component of the tensile force in the suspension ropes is transferred as a compressive force to the roadway girder, the vertical component of the tensile force is balanced by its weight. There are therefore strong and continuous from one end to the other end girders required. On the other hand, more stable and therefore heavier ropes and pylons are necessary for the comparatively heavy road girder. This design was used where the subsoil did not appear to be sufficiently solid to absorb the horizontal tensile force acting on the anchor blocks
The term is also used for cable-stayed bridges when the stay cables are bundled into a belt . Some truss bridges are also referred to as bridle bridges .
Examples are:
- Glienicke Bridge , steel bridge with truss between stiffening girders and top chord, 1907
- Krefeld-Uerdinger Bridge , suspension bridge, 1936
- second Reichsbrücke Vienna, suspension bridge, 1937
- Friedrich-Ebert-Brücke (Duisburg) , suspension bridge, 1954
- Paseo Bridge , suspension bridge, 1954–2010
- various cable-stayed bridges built by Riccardo Morandi :
- Maracaibo Bridge , 1962
- Polcevera Viaduct , 1967
- Bridge over the Wadi al-Kuf , 1971
- Puente Pumarejo , 1974
- Metten Danube Bridge , cable-stayed bridge, 1981
- Konohana Bridge , suspension bridge 1990
