Proceedings of Meetings on Acoustics Vibration isolation design of railroad tracks within Ankara high speed train station --Manuscript Draft-- Manuscript Number: POMA-D-15-00043R1 Full Title: Vibration isolation design of railroad tracks within Ankara high speed train station Article Type: ASA Meeting Paper Corresponding Author: Mehmet Caliskan, PhD Middle East Technical University Ankara, Ankara TURKEY Order of Authors: Salih Alan Mehmet Caliskan, PhD Abstract: Ankara serves as the hub for high speed railway operations within Turkey. A new station building of nine stories in total, which incorporates a shopping mall and a hotel inside, is currently under construction. Need arises for controlling vibrations due to passing trains through the building. Finite element model of the building is developed by commercial software. The interaction of the building with the foundation is represented by a number of spring and damper combinations whose characteristics are obtained from the existing knowledge of soil-structure interactions. Dynamic stiffness characteristics of the isolating layer under the railway slabs are sought. The Frequency Response Functions (FRF's) between several floors of the building and the base of the track are obtained from the finite element model, to be coupled with FRF's of the train-track-isolating layer system. Vibration isolation design is carried with respect to vibration criteria in Turkish environmental noise regulations.
