this paper describes a series of laboratory model tests on strip footings supported on unreinforced and geogrid-reinforced sand with an inside void. the footing is subjected to a combination of static and cyclic loading. the influence of various parameters including the embedment depth of the void, the number of reinforcement layers, and the amplitude of cyclic load were studied. the results sh...

Abstract. New systematic experiments reveal that the flexural strength of saline S2 columnar-grained ice loaded normal to columns can be increased upon cyclic loading by about a factor 1.5. The were conducted using reversed over ranges frequencies from 0.1 0.6 Hz and at temperature −10 ∘C on two salinities: 3.0 ± 0.9 5.9 ‰. Acoustic emission hit rate during cycling increases with an increase in...
