Methodology for the Experimental Evaluation of Frequency Response Functions in the Frame of Railway-induced or Construction-induced Groundbourne Vibration
نویسندگان
چکیده
In this paper, a methodology for the experimental evaluation of mechanical vibration frequency response functions in the framework of groundbourne railway-induced and construction-induced vibration predictions is presented. This methodology is based on a device specifically designed for the excitation of railway superstructures. The device can be used also to excite the ground with the aim of obtaining ground/building frequency response functions. The resulting frequency response functions can be used to feed prediction empirical models with specific in situ results or to characterize the system by performing an inversion process over a theoretical model of it, among other applications. Two examples of this methodology applied for the experimental determination of frequency response functions and subsequent system characterization are presented.

Effect of Rail Corrugation on the Amount of Train Induced Vibrations near a Historical Building
The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...

Abstract General faults in regular electrical railways system could be detect by implementing the specific protection functions such as ground fault or sensitive earth fault. Otherwise, in ungrounded electrical railway systems which using both feeding and return contact rail at the same time, fault detection cannot done with above-mentioned function. Due to recent growth in electrical railway ...
متن کاملEvaluation of TLD Performance in Reducing the Seismic Response of Structures
Tuned Liquid Dampers (TLD) are among passive control devices that have been used to suppress the vibration of structures in recent years. These structures must be adequately presentable as an equivalent single degree of freedom system with long fundamental period. The TLD, located at the top floors of the structure, can dissipate the external input energy into the system through the sloshing ef...
