Horstwalde beam test Having a hard working day in Horstwalde to try different non destructive techniques for beam monitoring. The tested beam Ultrasonic - Coda wave Test Sending and receiving Ultrasonic signal in embedded sensors to check any changes inside the concrete during the loading test. Ultrasonic Signal Digital image correlation Check the progression of cracks during loading by measuring the changes in pictures. Stereo-photogrammetry Gives exact position of selected points before, during and after loading test. Fiber optics Give the strain and the frequency of vibration during
