| Abstract: | For the responses of bridge piers and pile foundations in deep water during earthquakes,hydrodynamic pressures of the waterflow acting on the structure and back action of structure deformation on waterflow belong to the classical close fluid-soild interface coupling.A 3D close waterflow-structure coupling finite element model is established,in which the Navier-Stokes equation described by arbitary Lagrange-Euler format is employed to control the waterflow movement.Dynamic responses of cylindrical structres ... |
| Keywords: | close fliud-solid coupling structure in water dynamic effects of waterflow hydrodynamic pressure arbitary Lagrange-Euler format |
