Dynamic behaviour of mono bucket foundations subjected to combined transient loading

This article presents the results from small scale testing, investigating the effect of transient combined loading of a bucketfoundation. The tests are performed inside a pressure tank at Aalborg University, Denmark. The bucket foundation was installed in dense water saturated sand and transient loads were applied. The loading rate ranges from very slow, giving a drained response, to very fast, giving an undrained response. A factor of 25 was found between the drained and undrained bearing capacity
