Strategy of scaled modeling for underwater shaking table tests on cylindrical marine structures under coupled earthquake and wave–current action: A review

Abstract

AbstractMarine structures located in earthquake‐prone areas may be subjected to coupled earthquake and wave–current action and the underwater shaking table (UST) model test is one of the most effective methods to investigate the dynamic responses of them. However, the strategy of scaled modeling, including the selection of similitude criterion and the implementation of it, plays an important role in the test design, and hence influences the accuracy of response predictions of the prototype. This paper presents a comprehensive review of the strategy of scaled modeling utilized in UST model tests on marine structures subjected to coupled earthquake and wave–current action. The key performance parameters of USTs in service and being built in the world are first introduced. Then, the strategies of scaled modeling adopted in existing UST model tests of bridges, offshore wind turbines, submarine pipelines, and submerged floating tunnels are summarized. Following this, the applicability of current similitude criteria for UST model tests for different research focuses is fully discussed and the specific measure to realize the similitude criteria is concluded. Finally, recommendations for future work on similitude criteria are set out, providing insights into the improvements of the applicability and accuracy of the similitude criteria for UST model tests.
