摘要:
The time-domain wave method is adopted to achieve oblique incidence of earthquake waves based on the basic theory of viscoelastic boundary, combining with ABAQUS and FORTRAN program. A three-dimensional finite element integral computation model is established. The integral computation model consists of single layer reticulated cylindrical shell, pile and foundation soil. The seismic responses of the single layer reticulated cylindrical shell are analyzed considering different incidence angles of earthquake waves and pile-soil-structure interaction (PSSI). The results indicate that the seismic response of the piles is larger than the soil under the action of seismic waves with the range of incidence angel from 40° to 60°, and the seismic response of the outside piles is greater than the inner piles. The seismic response of the pile-soil-single layer reticulated cylindrical shell is not always the largest for the vertical incidence of earthquake waves. The horizontal seismic response of pile-soil-single layer reticulated cylindrical shell appears maximum values under the action of seismic waves with the range of incidence angel from 45° to 60°. The effects of different incidence angles of earthquake waves on the pile-soil-single layer reticulated cylindrical shell should be considered in seismic analysis. ©, 2015, Nanjing University of Aeronautics an Astronautics.
