| Abstract: |
Strengthening of bridges for compliance to new codes is nowadays quite usual, but some innovative solutions have to be found for economic reasons, when loads increase due to widening or seismic actions is huge and has a strong impact on foundations, or when other parameters such as vibrations need to be considered. Freyssinet’s solution on 2 projects, Binh Trieu Bridge in Vietnam and Ayala Bridge in Philippines is a complete change of static scheme: isostatic bridges are transformed into hyperstatic bridges or portal frame mixing together: new elements of concrete, additional prestressing, dampers, change of bearing conditions, with only one goal “reduction of global cost of strengthening solution.” |
