Estimation of the dynamic response of a slender suspension bridge using measured acceleration data
Petersen, Øyvind Wiig; Øiseth, Ole; Lourens, Eliz-Mari (Journal article; Peer reviewed, 2017)Suspension bridges with very long spans and slender designs are susceptible to large-amplitude dynamic excitation. Monitoring systems installed on bridges can provide measurement data (e.g. accelerations) and therewith ... -
Estimation of the full-field dynamic response of a floating bridge using Kalman-type filtering algorithms
Petersen, Øyvind Wiig; Øiseth, Ole; Nord, Torodd Skjerve; Lourens, Eliz-Mari (Journal article; Peer reviewed, 2018)Numerical predictions of the dynamic response of complex structures are often uncertain due to uncertainties inherited from the assumed load effects. Inverse methods can estimate the true dynamic response of a structure ... -
Force identification and response estimation in floating and suspension bridges using measured dynamic response
Petersen, Øyvind Wiig (Doctoral theses at NTNU;2019:88, Doctoral thesis, 2019)The trend of constructing bridges that are longer, more slender, and more flexible increases the importance of the assessment of dynamic behavior. Herein, it is imperative to have a good understanding of the environmental ... -
Full-scale identification of the wave forces exerted on a floating bridge using inverse methods and directional wave spectrum estimation
Petersen, Øyvind Wiig; Øiseth, Ole; Lourens, Eliz-Mari (Journal article; Peer reviewed, 2019)The dynamic behaviour of long-span bridges is governed by stochastic loads from typically ambient excitation sources. In real life, these loads cannot be measured directly at full scale. However, inverse methods can be ... -
Inverse identification of buffeting and self-excited wind loads on the {Hardanger} bridge from acceleration data
Petersen, Øyvind Wiig; Øiseth, Ole Andre; Nord, Torodd Skjerve; Lourens, Eliz-Mari (Chapter, 2019)The traditional wind load assessment for long-span bridges rely on assumed models for the wind field and aerodynamic coefficients from wind tunnel tests, which usually introduces some uncertainties. It is therefore desired ... -
Investigation of dynamic wind loads on a long-span suspension bridge identified from measured acceleration data
Petersen, Øyvind Wiig; Øiseth, Ole Andre; Lourens, Eliz-Mari (Journal article; Peer reviewed, 2020)The traditional wind load assessment for long-span bridges relies on assumed models for the wind field and aerodynamic coefficients from wind tunnel tests, which usually introduce some uncertainties. Recent studies have ...
