On-line identification of non-linear hysteretic structural systems using a variable trace approach.

On-line identification of non-linear hysteretic structural systems using a variable trace approach.

In this paper, an adaptive on-line parametric identification algorithm based on the variable trace approach is presented for the identification of non-linear hysteretic structures. At each time step, this recursive least square based algorithm upgrades the diagonal elements of the adaptation gain ma...
