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 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 6.5mm at 4MN load.
