Joint parameter-input estimation for virtual sensing on an offshore platform using output-only measurements

•A recursive window-based Bayesian inference approach is formulated and validated.•It is implemented for joint input-parameter estimation of an offshore structure.•Strain time histories at hotspots are accurately predicted through virtual sensing.•The proposed method outperform modal expansion metho...
