TL;DR: The passage of seismic waves through the soil surrounding a pile imposes lateral displacements and curvatures on the pile, thereby generating "kinematic" bending moments even in the absence of a su...

TL;DR: In this paper, a field investigation was carried out around the Tokyo Bay area following the 2011 Mw 9.0 Tohoku (Japan) earthquake, and first-hand observations related to uplift of manholes, settlement of ground, performance of buildings and bridges and the effects of ground improvements are also presented.

TL;DR: In this article, the authors investigated the role of soil in the collapse of the elevated Hanshin Expressway during the 1995 Kobe earthquake, and found that the impact of soil on the seismic performance of the bridge was multiple: first, it modified the bedrock motion so that the frequency content of the resulting surface motion became disadvantageous for the particular structure.

TL;DR: In this article, the authors investigated the seismic response of groups containing nonvertical piles, including the lateral pile-head stiffnesses, the "kinematic" pile deformation, and the "inertial" soil-pile-structure response.

TL;DR: In this article, the sensitivity of 2D wave effects to crucial problem parameters, such as the frequency content of the base motion, its details, and soil nonlinearity, was explored.
