The dynamic responses of submerged floating structures undergoing vortex-induced vibration and seismic excitation were numerically investigated. The tube and tethers of submerged floating structures were assumed as an Euler-Bernoulli beam and the hinged supports of the tube, respectively. The wakes behind the tube were regarded as distributed oscillators. With the consideration of the fluid-structure...
The aspect ratio of submerged floating tunnel (SFT), i.e. the ratio of length to diameter, is usually as large as 102 to 103, which means the behavior of SFT would like a slender cylinder restrained by tethers. Although SFT is usually placed under the water surface at a certain depth, surface wave has important influence on its dynamic response due to the slenderness. This paper performs analyses...
