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. 410 0$aMechanik, Werkstoffe und Konstruktion im Bauwesen,$x2512-3246 ;$v65 606 $aBridges$xDesign and construction 606 $aBridges$xLive loads 606 $aBridges$xTesting 615 0$aBridges$xDesign and construction. 615 0$aBridges$xLive loads. 615 0$aBridges$xTesting. 676 $a624.25 700 $aFirus$b Andrei$01312206 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 912 $a9910659491503321 996 $aA Contribution to Moving Force Identification in Bridge Dynamics$93030785 997 $aUNINA LEADER 01465oam 2200421Ia 450 001 9910695918403321 005 20200601131201.0 035 $a(CKB)5470000002374620 035 $a(OCoLC)67129150 035 $a(EXLCZ)995470000002374620 100 $a20060419d2006 ua 0 101 0 $aeng 135 $aurmn||||m|||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aMicropaleontology of selected wells and seismic shot holes, northern Alaska$b[electronic resource] /$fby Michael B.
