DEFORMATION ANALYSIS application example

Load Test of a Stone Arch Bridge

The deflection of a stone arch bridge at a loading test is measured with Q400 DIC system.The bridge span is 14m.

The bridge is loaded with 600MN which is similar to 10 train cars.
The natural stone pattern is used for the correlation. The images shows the deflection as grid with 100x amplification. The max. bending at the center of the bridge was only 6.5mm at 4MN load.

This application example shows that spatially resolved deformation measurement is possible with high accuracy even with large image fields.
