Modal testing and FE model tuning of a lively footbridge structure [PDF]
, 2006 Despite huge advances in numerical modelling of civil engineering structures in recent decades, finite element models for footbridges should still be developed and used with caution when evaluating modal properties of these structures.

Structural model updating and prediction variability using Pareto optimal models [PDF]
, 2008 A multi-objective identification method for structural model updating based on modal residuals is presented. The method results in multiple Pareto optimal structural models that are consistent with the experimentally measured modal data and the modal ...

Modal parameters identification and monitoring of two arches [PDF]
MATEC Web of Conferences, 2015 The paper presents the results of the modal parameters identification and of the continuous monitoring of two arches built in the new area of Expo 2015 in Milan. The activities on the arches were performed during the erection stage and they were planned as a consequence of preliminary studies performed at Politecnico di Milano wind tunnel, that ...
