Development of a signal processing tool to remove vehicle induced vibration signals from recorded seismic data for the vibration based SHM

摘要：

One of the major problems without satisfactory solutions in SHM is the fact that environmental changes are responsible for changes in features of interest as much as the damage itself.Especially for bridges,vehicular vibration signals may make the recorded seismic data difficult to use.The objective of this paper is to apply signal processing technology to remove vehicle vibration signals form contaminated recorded seismic response data of bridges.The paper presents the corresponding assumptions and preliminary method of the signal processing to solve this problem.An example application of this method to the recorded data from a bridge with a vehicle passing during a weak seismic event is given in the paper.Brief validation analysis and discussion are also presented.
