Dynamic monitoring of a long span arch bridge
WebJan 16, 2024 · The bridge was recently built across the Potenza river, on the No. 77 main road in Villa Potenza, close to the town of Macerata in central Italy and is composed by a main span (arch) of about 115 m and by one approaching viaduct at each side, constituted by continuous steel–concrete composite decks connected to that of the arch span. WebDec 18, 2009 · This paper presents the study on modal identification of the bridge. The dynamic properites including modal frequencies, mode shapes and damping ratios are extracted from the ambient responses. Two identification methods are employed including the enhanced frequency domain decomposition and the stochastic subspace identification.
