Étude de la superstructure d'un pont droit à poutres multiples en béton précontraint

Abstract

The aim of our work is to study a post-tensioned pre-stressed concrete multi-beam bridge with a total length of 134 m and a width of 10 m. The deck consists of 4 spans with 7 main beams per span, supported by 3 intermediate piles and two abutments at the ends. The beams are surmounted by a reinforced concrete slab. The study of the deck was carried out using the ROBOT STRUCTURAL ANALYSIS 2015 calculation software. On the basis of the results obtained on the transverse and longitudinal distribution of the loads and overloads applied on the deck, the design of the different elements constituting the deck namely the layout of the pre-stressing cables, the reinforcement of the beams , the slab and the end cross-beams and the design of the support devices, have been carried out
