| Abstract: |
This paper presents an innovative footbridge consisting in an arch in UHPFRC with filling in expanded clay grains crushed and spandrel walls in gabion. The analysis of Béziers’ architectural heritage leads to propose an innovative design concept: build a bridge without any dilatation joint and bearing, resort to a millenary technology but adapt it to a contemporary material, the Ultra-High- Performance Fibre-Reinforced Concrete (UHPFRC). The repetitive use of similar elements in the arch allows minimising the incidence of formwork complexity and consequently, allows respecting the maximum overall costs. The footbridge has a main span around 36 m and a 3,5 m effective width. |
