Stiffness and load sharing characteristics of piled raft foundations subjected to dynamic loads
TL;DR: A substructuring method-based soil structure interaction (SSI) analysis model is employed to study vertical and horizontal dynamic impedances of piled rafts (PR) in homogeneous and layered soil conditions.

Three-dimensional numerical analysis on seismic behavior of soil-piled raft-structure system
TL;DR: In this paper, the authors investigated the seismic behavior of piled raft foundation supporting structural system embedded in very soft clay encompassing variations of different influential parameters, such as flexibility of raft, pile spacing to diameter ratios, and asymmetry in pile length.

Influence of soil flexibility and plan asymmetry on seismic behaviour of soil-piled raft-structure system
TL;DR: In this article, a new seismic design guideline for asymmetric single and multi-storied structure supported on combined piled raft foundations (CPRF) embedded in soft clay is proposed.

Effects of Tunneling-Induced Ground Movements on Stability of Piled Raft Foundation: Three-Dimensional Finite-Element Approach
TL;DR: In this article, the authors discuss the need to construct tunnels within the vicinity of high-rise buildings supported on piled raft foundations, as a consequence, ground movements must be taken into account.

Response of Batter-Piled Raft Foundations with Different Superstructures during Seismic Events: Outcomes from Shaking Table Tests
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).

Dynamic impedances of pile groups with embedded caps in homogeneous elastic soils using CIFECM
P.K. Emani,B. K. Maheshwari +1 more
TL;DR: In this paper, a general three-dimensional finite element procedure is developed for the dynamic analysis of pile groups with caps embedded in isotropic homogeneous elastic soils, and the dynamic impedances of 2×2 pile groups are presented, for different spacing of piles and thickness of the pile-cap with different embedment ratios.

Seismic response of pile-raft-clay system subjected to a long-duration earthquake: centrifuge test and finite element analysis
TL;DR: In this paper, a series of seismic centrifuge model tests were performed to study the behavior of pile groups in soft kaolin clay, and several small-scale pile-raft models were fabricated, ranging from a 2×1 to a 4×3 pile group.

Seismic response of an urban bridge-support system in soft clay
TL;DR: In this paper, the numerical simulation of an instrumented urban bridge support and its foundation system was conducted, where the bridge works as a deck in a surface subway station and was built 12-yr ago in the so-called Lake Zone in Mexico City, where very soft clays, exhibiting low shear strength and high compressibility prevail.
