dc.description.abstractThe problem of jointly estimating the input forces and states of a structure from a limited number of acceleration measurements is addressed. Utilizing a model-based joint input-state estimation algorithm originally developed for optimal control problems, minimumvariance unbiased estimates of the modal displacements and velocities of a structure as well as the dynamic forces causing these responses, are obtained. The proposed algorithm requires no prior information on the dynamic evolution of the input forces, is easy to implement, and allows online application. Its accuracy and effectiveness are demonstrated using data from a laboratory experiment on an instrumented steel beam and an in situ experiment on a footbridge.en
