Abstract The Modal Phase Collinearity (MPC) is a modal indicator designed to decide
whether the mode shape used in its computation is a real or complex-valued vector. Its …

In stochastic subspace methods, the modal analysis results are highly dependent on the
dimensions of the Hankel matrix. Increasing the dimensions of the Hankel matrix (especially …

Vibration analysis seeks to extract the modal parameters of a mechanical system by means
of experimental measurements. Natural frequencies, damping ratios and mode shapes are …

Determining the natural frequencies and damping ratio is the most important step in the
dynamic behaviour analysis of fixed jacket structures, such as offshore wind turbines and …

Despite advancements in Kalman filtering and the dozens of published works on the subject,
the performance of Kalman filtering in terms of structural damage quantification is limited to …

Wave loading of offshore structures such as oil rigs and wind turbines are governing for the
design of these structures. Since the environmental conditions may change during the …

Stochastic subspace identification (SSI) is a process that linearizes the identification
problem by utilizing singular value decomposition (SVD) and QR factorization. This …

Based on the linearization of the structure's vibration equation in the state space, the
stochastic subspace (SSI) approach is often used for system identification in the time domain …

Abstract The Modal Phase Collinearity (MPC) is a modal indicator designed to decide
whether the mode shape used in its computation is a real or complex-valued vector. Its …

Load effects from breaking waves on offshore structures may be a driving point for the
design. It is hence important to assess the likelihood of occurrence along the magnitude of …
