Verification of joint input-state estimation by means of a full scale experiment on a footbridge

This paper presents a verification of a state-of-the-art joint input-state estimation algorithm using data obtained from in situ experiments on a footbridge. A dynamic model of the footbridge is based on <br/>a detailed finite element model that is calibrated using a set of experimental modal characteristics. The joint input-state estimation...

Verification of Joint Input-State Estimation by In Situ Measurements on a Footbridge

An existing joint input-state estimation algorithm is extended for applications in<br/>structural dynamics. The estimation of the input and the system states is performed in a minimum-variance unbiased way, based on a limited number of response<br/>measurements and a system model. The noise statistics are estimated, as they are<br/>essential for...
