Protocolli di indagine su impalcati in c.a.p. con schema in semplice appoggio

Abstract

This study introduces a procedure for the structural health assessment of simply supported prestressed concrete bridge decks, based on the application of multivariate analysis techniques to accelerometric data. The approach establishes a comparison between the dynamic behavior of the investigated spans—characterized through experimental operational modal analysis—and that of a benchmark span, identified on the basis of static load test results. The proposed methodology is demonstrated through a representative case study.
