| Abstrait: |
The collapse of the intermediate part the União Bridge on April 6, 2019 interrupted the operation of the main road system of Belem, the most important metropolitan of the Northern state of Para, Brazil. In order to reduce the socioeconomic impacts to the region, the Secretary of Transport immediately carried out the construction of the 268m stay cable bridge to rehabilitation this transportation system. This solution had the advantage of a single mast in the middle of the collapse span, in a position where there were no bents and foundations of the original construction, accelerating the construction. Besides, the stay-cable structural system also has great kinetic energy dissipation capacity from large impacts, being an addition to the robustness introduced by mast foundations and the redundancy of the stay cables system. |
