Abstract

The vehicle scanning method (VSM) proposed by Yang and co-workers in 2004 [1] is an indirect approach for bridge measurement. Normally, the test vehicle’s recorded response was used to extract the bridge properties. Two issues eixst in this regard. One is the masking effect of the vehicle’s self frequencies on the bridge frequencies, making the latter indistinguishable. The other is the pollution effect caused by pavement roughness, which becomes even worse as the vehicle speed increases. The two issue can be overcome through the combined use of the vehicle-bridge contact response (for removing vehicle’s frequencies) and the residual response (for eliminating the roughness effect) generated by two wheels. The purpose of this paper is describe the essence of such an approach.
