TL;DR: In this paper , a series of shaking table tests, including vertical and nonvertical configurations, were conducted, and the effects of superstructure frequency and pile angle on the seismic performance of the models were examined under a wide range of accelerations (0.2 − 0.7 g).
Abstract: The performance of batter-piled raft systems during seismic events continues to be a major concern. In response, a series of shaking table tests, including vertical and nonvertical configurations, were conducted, and the effects of superstructure frequency and pile angle on the seismic performance of the models were examined under a wide range of accelerations (0.2–0.7 g). Smaller bending moments, horizontal displacements, and rotations were captured for the nonvertical models, so the application of batter piles is reliable under seismic conditions. The maximum bending moment in the vertical models was recorded to be 8 times greater than in the batter piles at the lowest level of ground motion. Thus, the performance of the system was more sensitive to the frequency of the superstructure for vertical piles.
