“…Lekidis et al [28], in particular, identified modes of vibration at the range 0.37-0.54 Hz in a relatively small (middle span of 215 m) cable-stayed bridge in Greece, a result consistent with both FEM predictions and results of observations with a robotic total station. Their measurements were based on a system of two base receivers, and centimetre to sub-centimetre level accuracies were claimed.…”

“…In the second case, Celebi and Sanli [27] found a similarity in the estimates of the natural frequency of a building deduced from GPS recordings and an accelerometer record during an earthquake. Lekidis et al [28] also arrived at a similar conclusion on the basis of the comparison of the spectra of a suspended bridge derived from independent accelerometer, GPS and robotic total station data.…”

“…The above estimates are realistic, but do not represent the upper bound of the linear or angular velocities that can be recorded, or of the accuracy of the GPS; using more sophisticated software and hardware a higher accuracy can be obtained (Ge et al [9]; Lekidis et al [28]). …”

“…Li et al [33] presented a new and practical method for the deformation monitoring of the Yellow River Shengli Bridge by the integration of GPS and total station technology. Lekidis et al [34] studied the dynamic characteristics of the Evripos cable-stayed bridge using total station and GPS, and the results showed that whilst the robotic total station solutions yielded a precision of 2-3 mm for absolute height displacements, the GPS results indicated that the bridge deck was not well suited for high precision monitoring due to the shading and diffraction effects caused by the steel cables.…”

Today, long-span bridges are being designed to be more flexible and to resist extensive impacts from changes in temperature, severe wind gusts and earthquake tremors. Structural responses (especially displacement) of bridge structures are becoming increasingly important for the finite element (FE) modal updating, structural response prediction and safety evaluation. Methods of global displacement sensing were developed for these needs. This paper presents an overview of current research and development activities in the field of bridge health monitoring using the global positioning system (GPS). The GPS monitoring technology and its accuracy assessment method are also briefly described. Finally, existing problems and promising research efforts in the GPS based bridge health monitoring are discussed. global positioning system (GPS), structural health monitoring (SHM), bridge, measurement Citation: Yi T H, Li H N, Gu M.

“…However, the monitoring of soil-abutment interaction using vibration signals has been lacking. The detection and monitoring of soil-abutment contact pressures are critical for abutment design and maintenance management [3][4][5][6][7][8][9][10][11][12][13][14]. Investigations to examine the effect of the earth pressure conditions on vehicle-induced soilstructure interactions and to quantify the amplification and frequency content of the vibrations transmitted could be instrumental in assessing the dynamic characteristics of the related structures.…”

This paper aims to explore fundamental characteristics of bridge vibration spectra to potentially evaluate soil-abutment interactions and changes in abutment earth pressures. To this aim, the bridge response to the excitation of an approaching vehicle on road is utilized to evaluate the transmissibility of the road-soil-abutmentbridge (r-s-a-b) path. By comparing the FFT spectrums of bridge acceleration responses before and upon a vehicle traversing over an abutment, we found that the response spectrum consists of specific frequency of vehicle excitation, even though the bridge response before vehicle traversed over the abutment has a much smaller magnitude. This suggests that the bridge response before the vehicle traversed over the abutment is sensitive enough to be used to characterize the dynamic features of r-s-a-b transmissibility. Hilbert-Huang Transform method is used to extract the non-stationary information of the moving vehicle excitation from the bridge responses to characterize the r-s-ab transmissibility. It is found that specific signature associated with the specific frequency of vehicle excitation can be extracted from the Hilbert spectrum of empirical modal decomposition signals, and this signature could be readily quantified as a monitoring index which exhibits time-varying property.
