Popis:	Prikazuje se postupak proračuna prednapetih provješenih mostova s ciljem postizanja zahtijevane geometrije rasponskog sklopa pod djelovanjem vlastite težine prema uvjetu uporabljivosti pješačkih mostova. Optimizira se potreban broj nosivih natega za montažu mosta i dodatnih natega za naknadno prednapinjanje. Rezultat toga je definiranje postupka montaže kojim je određena potrebna duljina natega, njihov oblik i sila na mjestu sidrenja pod djelovanjem njihove vlastite težine. The analysis of stress-ribbon bridges, aiming at attaining the required bridge superstructure geometry under dead weight action, based on the serviceability criteria for footbridges, is presented. The required number of tendons for the construction of the bridge and the number of additional tendons needed for post-tensioning, is optimized. The final result is the choice of the appropriate construction procedure, which defines the required tendon lengths, tendon shapes, and the prestressing force at the anchoring point under the action of their self-weight.
