“…To authors' knowledge, there were several field damage experiments conducted in recent two decades for testing VBDD techniques on the following bridges: I-40 Bridge, a steel plate girder bridge (Farrar et al 1994); Z24 Bridge, a pre-stressed concrete (PC) box girder bridge (Kramer et al 1999); Romeo Bridge, a PC box girder bridge (Huth at al. 2005); Kurumakaeri Bridge, a steel truss bridge (Furukawa & Otsuka 2008); Dogna Bridge, a reinforced concrete (RC) girder bridge (Dilena & Morassi 2011); Torigai Bridge, a steel truss bridge ); a steel truss bridge (no name given) (Yoshioka et al 2011); Deutsche Bank Bridge, a PC slab bridge (Maas et al 2012); and Avenue John F. Kennedy Bridge, a PC box girder bridge (Maas et al 2012). Although many valuable results have been yielded, the number of field experiments is still insufficient to guarantee the practicability and reliability of existing VBDD techniques on real bridges.…”

“…Damage sensitive features are extracted by fitting a mathematical model to the responses measured. Despite various successful applications [8,9], the effectiveness of these linear methods is sometimes limited. Firstly, they tend to show a rather low sensitivity [10].…”

“…(4) The shifts of dynamic parameters such as natural frequencies, damping ratios, mode shapes, and other relevant numerical parameters may indicate damage information. (2,5,6) However, dynamic parameters are easily effected by environmental factors such as temperature and frost. (7,8) To comprehend the effect of the environment on dynamic characteristics, the analysis of the variations of dynamic parameters in different seasons was carried out employing a wireless acceleration sensor network system.…”

In this study, a fundamental application of a wireless acceleration sensor network system was carried out by conducting two bridge vibration experiments in autumn and winter. Seasonal effects on the dynamic characteristics of a multispan ballasted prestressed concrete railway bridge were investigated by employing a wireless acceleration sensor network system as a basic study of structural health monitoring technology. The dynamic parameters of every single span, such as natural frequencies, damping ratios, and mode shapes, were determined from free damped vibration, which was caused by human jumping excitation. Owning to the excitation pattern limitation, three modes were obtained in the experiments. A three-dimensional (3D) finite element (FE) model was made to show the rationality of the experimental result. Comparison of the autumn and winter experimental results showed that the natural frequencies of the bridge were significantly higher in winter than in autumn. The frozen ballast and frost on the deck and walkway were revealed to be reasonable explanations for this phenomenon. Meanwhile, the variations of damping ratios were not as simple as those of the natural frequencies. No variation regularity of damping ratios was obvious.
