Shock-safe fastenings for shelter equipment must be capable transferring transient forces into cracked concrete with moderate displacement and without pullout. To evaluate suitable metal anchor systems, Labor Spiez performed shock tests with metal anchors with varying shock loads. The results of a large number of anchor tests with different shock loads and different anchor types are presented. The analysis of the results shows that the anchor slip depends only on the acting shock load.
