Abstract

This paper presents two applications of joint input-state estimation in structural dynamics. The considered joint input-state
estimation algorithm relies upon a limited set of response measurements and a system model, and can be applied for online
input and state estimation on structures. In the first case, the algorithm is applied for force identification on a footbridge. The
second case shows an application where strains in the tower of an offshore monopile wind turbine are estimated. In both cases,
real measured data obtained from in situ measurements are used for the estimation. The dynamic system model, used in the
estimation, is for both case studies obtained from a finite element model of the structure. The quality of the force and response
estimates is assessed by comparison with the corresponding measured quantities.
