- Two series of model tests were performed.
- A new compliant multi-legged model system was designed.
- Test techniques and the experimental results were provided.
- The important test phenomena were discussed.
Two series of model tests were performed to investigate the dynamic ice loads on two types of four-legged jacket platforms and the consequently structural responses. The first test series was carried out with cylindrical models and the second test series with conical models at the water level. To simulate the ice induce vibrations on multi-legged structures, a new series of test equipments was designed. The ice load on each model leg, structural displacements in three directions, and foundation reactions in two directions were measured during the tests. Different ice failure modes and structural responses were observed for different ice conditions and structural stiffness values. This paper provides a description of the test techniques and the experimental results. The important test phenomena are also discussed in this paper.
