TL;DR: In this paper, a simple and fast evaluation method of soil-structure interaction (SSI) effects of embedded structures via a cone model is presented via the evaluation of the impedances and the effective input motions at the bottom of an embedded foundation.

TL;DR: In this paper, the effects of soil loading on large diameter, close fitting, non-bonded, flexible sewer liners as typified by "cured-in-place pipes" (CIPP) are investigated.
Abstract: This paper presents an experimental study of the effects of soil loading on large-diameter, close-fitting, non-bonded, flexible sewer liners as typified by ‘cured-in-place pipes’ (CIPP). CIPP is the process whereby a polymeric pipe lining is cast directly against the wall of a deteriorating sewer pipe. The transfer of soil loading to CIPP liners is strongly influenced by the interaction between the existing host pipe and the surrounding soil. In adjusting to deterioration events of the host pipe and possible void formation in the soil, the existing pipe-soil structure deforms and interacts with the liner inside it. By monitoring deformations of the liner and host structure the magnitude of load transfer can be inferred. The paper describes 1/30th scale physical models tested in dry sand under 30g of centrifugal acceleration. The models included: (a) a host pipe with two simulated modes of deterioration; (b) an instrumented close-fitting, non-bonded, flexible liner; (c) voids in the soil; and (d) moving, h...

TL;DR: In this article, the authors describe procedures to evaluate the dynamic properties of test structures subject to forced vibration testing and demonstrate their application using data from two test structures supported on shallow foundations that have been used in forced vibration tests and that have recorded earthquakes.

TL;DR: In this paper, a numerical analysis of the interaction between shallow tunnelling and structure on surface is performed using the software Flac3D, based on three-dimensional finite differences.
Abstract: This paper presents a numerical analysis of the interaction between shallow tunnelling and structure on surface. The analysis is done using the software Flac3D, based on three-dimensional finite differences. The TBM tunnel excavation is simplified and is taken into account by volume loss. First, a reference calculation without structure on surface is presented. A numerical model coupling ground mass and structure on surface is then used to study the soil–structure interaction. The structure is composed by columns and floors, founded on a raft. The material has elastic properties of a reinforced concrete. Results are analysed in term of ground displacement on surface. The last part presents the influence of the structure stiffness on soil displacements on surface.
