On the assessment of the vibrational response of highly-skewed high-speed railway bridges. En Bridge Maintenance, Safety, Management, Digitalization and Sustainability - Proceedings of the 12th International Conference on Bridge Maintenance, Safety and Management, IABMAS 2024 (1199-1206), Copenhagen: CRC Press.978-103277040-6https://hdl.handle.net/11441/165010© 2024 The Author(s)The aim of this study is to evaluate the vertical vibrational response of simply-supported (SS) highly-skewed railway bridges. Configurations of interest are pre-stressed concrete girder deck bridges with and without end transverse diaphragms from conventional and High-Speed (HS) lines. Two detailed 3D Finite Element (FE) numerical models including the ballast track are implemented and updated from experimental modal data from two real bridges of approximately 15 and 25 m of span lengths. The evolution of modal parameters and maximum acceleration under passing trains is investigated for several variants of the reference models. Conclusions regarding the effect of skewness correlated with the execution procedure of the transverse diaphragms are finally extracted.application/pdf8 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess10.1201/9781003483755-139
