“…Zhang et al (2019f) also employed potential-based fluid elements to set up a threedimensional numerical fluid-structure interaction model to account for the hydrodynamic effects of a nonuniform bridge hollow pier submerged in a reservoir. Wei et al (2019e) assessed the dynamic responses of the deepwater rigid-frame bridge by underwater shaking table tests and numerical simulations and proposed a practical method for seismic design of deepwater rigid-frame bridge. Wang et al (2019h) proposed simplified formulas for the added mass of the round-ended and rectangular cylinders to estimate the hydrodynamic pressure on uniform vertical cylinder.…”

“…The existing studies show that the dynamic responses of the full bridge differ from those of the single pier due to the influence of the superstructure and the seismic differential effect as well as the traveling wave effect 50,59 . However, far fewer UST tests have been performed on the full bridge 49–51,59 .…”

Marine 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.

“…It is worth mentioning that seismic responses of deep-water CRFBs have attracted attention since the underwater crack occurred in the main pier of the Miaoziping Bridge (Wei et al 2022). Qiao et al (2022) conducted an in-depth parametric study of topographic effect on the seismic response and running safety of a train-bridge coupled system on a CRFB.…”

Continuous rigid-frame bridge (CRFB) is widely constructed in western China with high seismicity areas. To investigate the seismic response characteristics and whiplash effect mechanism of CRFBs under near-fault ground motions, this study selects a long-span CRFB with high piers as the prototype bridge and develops the nonlinear finite element model based on OpenSees. In this work, three groups of near-fault ground motions having forward directivity pulse, fling-step pulse and non-pulse are selected as seismic inputs. These records are intercepted using significant duration index and scaled to 0.2 g, 0.4 g, and 0.64 g, representing basic ground motions, frequent ground motions and rare ground motions, respectively. The study analyzes the seismic response characteristics of CRFBs and discusses the effects of bearing constraints, ground motion components and vertical excitations on the seismic responses. The numerical results show that the longitudinal vibration, transverse whiplash effect and vertical uplift behavior of main girder are main deformation characteristics of CRFBs. Compared with non-pulse earthquakes, the structural displacements, lateral drift angles, bearing deformations, internal forces and pounding effects all significantly increase under pulse-like earthquakes. There are spatial torsional effects in mid-span girder and main piers and pounding effects between girder ends and transition pier top. The perfectly-free and fixed bearings in transverse direction are not recommended for the seismic design of CRFBs. An optimal stiffness ratio in friction pendulum systems may exist that can minimize bending degree of the main girder. Furthermore, the side-span girder under pure longitudinal excitations can uplift that is closely  Long-He Xu
