Optical identification and modeling of the nonlinear dynamics of timber buildings – DYNATIMBEREYES

Submission summary

In various cities worldwide high-rise wood building represent a performant offer for sustainable cities and ecological transition. Dynamics of such structures highlights specific non linearities and relatively large vibration amplitudes. Building software and regulations are under evolution in order to allow higher and larger wood construction. Current experimental methods have several important drawbacks (access to the building, expensive experimental setup, long cable routing, time consuming measurements and important biases). Current software used for the modelling are based on linear assumptions even though experiments highlight nonlinear dynamics. DynaTimberEyes aims at initiating an innovative experimental and numerical methods for the analysis of high wood structures, able to model and identify quickly and accurately dynamics of wood towers. This method will be based on video measurements, nonlinear reduced order models and data assimilation methods (Kalman filters).
