On December 9th 2020 at 11:30 a.m., Professor Luca Caracoglia (Northeastern University, Boston, USA) will present the talk titled “Wind Load Uncertainty Effects on Long-Span Bridge Aeroelasticity: from Stochastic Dynamics to Artificial Intelligence Surrogate Models”, where the relevance of wind load uncertainty propagation on wind-induced bridge vibrations will be examined. In the first part, reduced-order models will be employed to estimate the stationary probability distribution of a generalized variable vector, simulating the wind-induced bridge response contaminated by various error sources. The second part will examine Monte-Carlo simulation algorithms for uncertainty quantification and to study the loss of performance in a long-span bridge, produced by wind-induced vibration. Finally, in the context of flutter instability, the study will introduce how Artificial Intelligence can be innovatively employed to estimate bridge flutter occurrence without requiring the direct solution of the equations of motion.
The webinar will be hosted at the Department of Civil and Environmental Engineering, University of Perugia, remotely via Microsoft Teams platform.
