Road bridge monitoring using digital image correlation
The paper considers problems, defects and methods of bridge span diagnostics. It is proposed to use the promising digital image correlation method based on laser speckle imaging and high-speed video recording during bridge testing. The analysis is given to test results of the bridge over the Burunduk River in the Tomsk region and its dynamic characteristics using the Faza-1T measuring system. Relative displacements of railway beam surface are determined under live loads when using digital image correlation. According to the analysis the experimental data, the digital image correlation method and described equipment are efficient for using them in sites.
