| Résumé | Potential continuation or acceleration of climate change could increase the risk of failure of critical bridge components or bridge systems. This paper present preliminary results of ongoing study investigating the impact of extreme climate loads, on the safety and serviceability of a curved-continue composite box-girders bridge. A four-span curved box-girder bridge was designed according to the Canadian Highway Bridge Design Code and simulated by a 3D nonlinear finite element model. The bridge is investigated for the effect of different levels of temperature and ice accretion combined with other gravity loads. The results show significant increases in the moments, high levels of stresses, and very large increase of longitudinal and vertical displacements at critical sections of the bridge superstructure. More research investigations are required to further investigate the safety of the bridge elements, connections, and the integrity of the bridge system. |
