The study presents technology which can decrease the vibration of railroad station via adopting a friction bearing system beneath a platform. The platform itself then constitutes a tuned mass damper system (TMD) as the bearing provides stiffness and damping of the TMD system. To increase the robustness of the TMD system, the bearing system with adjustable stiffness is utilized. The vibration reduction performance of the TMD system is verified via numerical analysis on an elevated railroad station known as having a structural type with highest noise and vibration level. The numerical analysis is performed using a commercial program, ABAQUS. The vibration analysis is performed considering vehicle-track-structure interaction. The result of the numerical analysis shows that the TMD technology can reduce significant amount of vibration of a railroad station.
