Abstract

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.
