Topic: Sensitivities and prerequisites of the application of the Energy Flux Analysis to high-rise structures excited by wind using in situ measurements


Description: As buildings become taller, more slender and lighter, structural engineers are increasingly faced with the consequences of the dynamic response of high-rise buildings excited by the wind. This response is limited by damping in the structure, but to date, damping can only be estimated by empirical damping predictors that show a large scatter. Therefore, there is a strong desire to obtain a further understanding of the damping behaviour in high-rise structures. Where classical damping identification techniques are not generally applicable and can only identify the total damping of a structure, the novel Energy Flux Analysis allows for damping identification of components of a structure. The Energy Flux Analysis is promising but is faced with uncertainties when applied to a high-rise structure using in situ measurements. This thesis focuses on the sensitivity of the Energy Flux Analysis to these uncertainties, using the New Orleans tower in Rotterdam as a case study.
