At the end of the ProBucket test programme , the largest test specimen in the almost 10-year history of the TTH was examined. With a diameter of 2400 mm, this test specimen was successfully installed in the centre of the foundation testing pit using vacuum and the load-bearing behaviour under cyclic loading was investigated.
In stark contrast to this is a previously unique buckling test on a true lightweight: a test specimen with a sheet thickness of 1 mm and a diameter of 1500 mm. This very sensitive bucket model was also installed using negative pressure. During the installation process, a stability failure occurred as planned due to buckling during penetration into the testing soil. For suction buckets as a steel structure, the installation process is particularly critical for structural safety. For the first time, buckling failure could be investigated on a large scale under combined, realistic boundary conditions.
We are delighted with this great result and would like to thank everyone who contributed to the success of this campaign.
