..., this superposition approach adopts Miner's rule, as the accumulated rotation is considered to be independent of the ordering of the cyclic load parcels. This paper examines the validity of this assumption for moment cyclic loading of suction caissons in sand, through a series of model tests involving both constant...

On the other hand, the phenomenon of ‘entrance of excess soil’ has long been reported and the residual strain values in test 2 are not unrealistic compared with soil recovery ranging from 100 to 154% observed by Hvorslev (1949) . Hvorslev believed the main cause...
