Abstract

The Tianjin West Railway Station, located along the Beijing-Shanghai high-speed railway, is an elevated structure and has been constructed as a novel, integrated bridge-station system. In this study, dynamic responses of this integrated train-track-railway station are computed using finite-element analysis (FEA) in conjunction with the adaptation of (analytical) system coupling techniques. In particular, a multi-rigid-body dynamics treatment of the train-track-railway system is given, based on coupling of displacements between the track and contact points of train wheels. Further, the corresponding dynamic equations of motion include considerations for nonlinear contact. Finite-element (FE) modeling of the Tianjin West Railway Station is carried out to compute modal and transient responses over a range of train passage scenarios. The analytical framework results support that (1) vibrations induced by train passages are predominately vertical; (2) vibrations are highly attenuated regardless of train passage speed; (3) such attenuation, in turn, diminishes the propensity for dynamic response of the integrated, elevated level, and roof components; and (4) the integrated structure satisfies applicable railway design-code requirements.
