Damping is a complex phenomenon in vibrating systems and is of interest to be understood and measured due to its important role in dynamic behaviour of the vibrating systems. The present work attempts to find out the damping ratio of a MERO-type double layer grid due to variations of the tightness of the bolts of the connections. The results of the 70 dynamic tests have been analysed and the effects of the variations of the bolt tightness on the damping ratio of the grid is discussed.
