Abstract: | In the present work, a two-phase analysis is used to assess the lateral movement of a tapered pile due to kinematic seismic
loading resulted from earthquakes. First, the free-field horizontal displacement of the ground due to earthquake is estimated
using available theory of wave propagation. Second, these estimated soil movements are imposed on the taper pile in a closed-form
solution to compute the pile response. The governing differential equation for an arbitrary pile segment is obtained, which
includes the free-field horizontal movement estimated from the first phase. The equation is solved explicitly to obtain the
horizontal deflection. Parametric studies show that tapered piles tend to be more flexible than uniform piles of the same
volume and length under earthquake loading, which is soundly interesting. |
