In this sense, this work provides a novel approach for identification of dynamic moving forces acting on a bridge structure. It seeks to find the optimal time dependent force values that minimize the difference between the computed and measured displacement and acceleration time histories for a limited number of sensor locations. The work also presents extensive experimental investigations of the developed method on real structures in operation, which consistently show that it can be successfully used on a wide range of applications: from small structures excited by rather low pedestrian forces up to the "heavy category" of a complete train passing a railway bridge. In this context, a set of particularities and limitations arising in the practical application of the method on real structures are also discussed. Andrei Firus studied civil engineering at the University "Politehnica" Timisoara, Romania and at the HTWG Konstanz - University of Applied Sciences, Konstanz, Germany. Between 2015 and 2021, he completed his PhD in structural dynamics at the Institute of Structural Mechanics and Design (Prof. Dr.-Ing. Jens Schneider), Technical University of Darmstadt, Germany. In 2020, he co-founded iSEA Tec GmbH in Friedrichshafen, Germany. Since then, he has been managing director of the company, which is active in the fields of structural design of lightweight structures, structural dynamics as well as monitoring and condition assessment of existing structures.Mechanik, Werkstoffe und Konstruktion im Bauwesen,2512-3246 ;65BridgesDesign and constructionBridgesLive loadsBridgesTestingBridgesDesign and construction.BridgesLive loads.BridgesTesting.624.25Firus Andrei1312206MiAaPQMiAaPQMiAaPQ9910659491503321A Contribution to Moving Force Identification in Bridge Dynamics3030785UNINA01398nam2 22003373i 450 TSA083350420231121125848.088061631329788806163136Ristampa20120331d2002 ||||0itac50 baitaitz01i xxxe z01n˜2: œDal pietismo al romanticismo(1700-1820)Ladislao MittnerTorinoEinaudi[2002]3 v.20 cm001LO106149452001 Storia della letteratura tedescaLadislao Mittner2001TSA08335052000 3Ladislao Mittner3001TSA08335082000 2Ladislao Mittner2001TSA10447092000 1Ladislao Mittner1Mittner, LadislaoRAVV00005207036990ITIT-0120120331IT-FR0084 IT-FR0017 Biblioteca Del Monumento Nazionale Di MontecassinoFR0084 Biblioteca umanistica Giorgio ApreaFR0017 TSA0833504Biblioteca umanistica Giorgio Aprea 52MAG 1 Coll P 191-2.2 52MAG 1 Coll P 191-2.3 52MAG 1 Coll P 191-2.1 52MAG 1 Coll P 191.2 52FLS0000280255 VMN RS A 2015052620150526 25 52Dal pietismo al romanticismo478659UNICAS
