Abstract

The present study outlines the application of smartphone and model updating in structural health monitoring by using vibration response data. The application of the approach has been shown for simply supported beams with uncracked and different crack configurations. Crack has been artificially generated at the time of casting using thin steel plate of 1.5 mm thickness. Finite element analyses have been carried out for uncracked and cracked beams. Laboratory tests were conducted using smartphone to obtain the natural frequencies of both damaged and undamaged beams with the help of accelerometer application software. Acceleration in the vertical direction of the cracked and uncracked beams was measured using this mobile application and thereafter, frequency response function curves have been obtained from this. At last, the model has been updated using bees algorithm to get more accurate results.
