dc.description.abstract | Finite-element-model updating allows reducing the discrepancies between the
numerical and the experimental dynamic behaviour of civil engineering
structures. Among the different methods to tackle the updating problem, the
maximum likelihood method has been widely used for practical engineering
applications. In this method, the updating problem is transformed into an
optimization problem where the relative differences between the numerical and
experimental modal properties of the structure are reduced via the modification
of the most relevant physical parameters of the model. However, this method
often presents the drawback of requiring high simulation times in order to
perform the updating process when dealing with complex structures. To
overcome this limitation, in this paper a novel hybrid Unscented Kalman Filter –
Harmony Search (UKF-HS) algorithm is proposed and its implementation details
are discussed. In order to validate such hybrid algorithm and further illustrate its
performance, the finite-element-model updating of a benchmark footbridge is
performed using two different approaches (single-objective and multi-objective)
and three different computational algorithms, namely: (i) genetic algorithms; (ii)
harmony search; and (iii) the novel UKF-HS hybrid algorithm. The obtained
results reveal that the proposed hybrid algorithm may be considered as an
adequate alternative tool to efficiently perform the finite-element-m | en_GB |
