| description | Considering a typical steel pipe pile-supported wharf as the research object, finite element analytical models of batter and
vertical pile structures were established under the same construction site, service, and geological conditions to investigate
the seismic dynamic damage characteristics of vertical and batter pile-supported wharf structures. By the numerical
simulation and the nonlinear time history response analysis of structure system and the moment–axial force relation curve,
we analyzed the dynamic damage characteristics of the two different structures of batter and vertical piles under different
seismic ground motions to provide reasonable basis and reference for designing and selecting a pile-supported wharf
structure. Results showed that the axial force of batter piles was dominant in the batter pile structure and that batter piles
could effectively bear and share seismic load. Under the seismic ground motion with peak ground acceleration (PGA) of
350 Gal and in consideration of the factors of the design requirement of horizontal displacement, the seismic performance
of the batter pile structure was better than that of the vertical pile structure. Under the seismic ground motion with a PGA
of 1000 Gal, plastic failure occurred in two different structures. The contrastive analysis of the development of plastic
damage and the absorption and dissipation for seismic energy indicated that the seismic performance of the vertical pile
structure was better than that of the batter pile structure. |
