“…As already observed in the literature [14], deamplification of the transfer function is observed for frequencies lower than the first RB7 frequency and amplification for higher frequencies. However, SSSI effect do not seem to be the main reason of differences observed between numerical simulations and measurements of RB7 response during NCOE.…”

Abstract. On the framework of the French research project SINAPS@, the main goal of this work is to assess the impact of different soil-structure interaction modeling strategies on the Unit 7 Kashiwasaki-Kariwa Nuclear Power Plant reactor building response during the Niigata Chuetsu-Oki earthquake mainshock. his actual nuclear power plant case-study was already investigated during the KARISMA (KAshiwazaki-Kariwa Research Initiative for Seismic Margin Assessment) international benchmark exercise on 2009 organized by the IAEA (International Atomic Energy Agency) and OECD/NEA, which concluded on the difficulty to correctly predict the Unit 7 Reactor Building response during the mainshock by considering available standard soil-structure interaction modeling. The modeling strategies investigated in this work include soil non-linearity, by considering a cyclic critical state elastic-plastic model, and structuresoil-structure interaction influence by directly considering a simplified model of the adjacent Turbine Building.All numerical simulations are performed using code aster Open source software. The comparison of results with recorded signals within the Unit 7 Reactor Building allow to emphasize some conclusions about the role of modeling assumptions. This paper gathers the research work conducted by EDF R&D in the SINAPS@ task 4.3 during the years

“…The importance of the first resonant frequency of the building of interest (i.e. RB7) was also observed on conducted numerical simulations of the SSSI NUPEC benchmark [14]. Therefore, from these results, considering SSSI can be relevant on frequency range lower than the first resonant frequency of the building, e.g.…”

“…A similar behaviour has been observed in the past see e.g. Luco and Contesse [3], Kobori and Kusakabe [4], and more recently by Alexander et al [12] in the case of the study of cross dynamic interaction of structures founded on surface foundations and by Padròn et al [25] in the case of nearby pile supported structures as well as in the laboratory and field tests on models of nuclear power plant buildings conducted by the Nuclear Power Electric Corporation (NUPEC) for investigating the dynamic cross interaction effects [26][27]. Figure 8 illustrates the stochastic response of the internal unit of the ViBa under the same input and soil profiles used for Figure 7.…”

This paper deals with the vibration control of existing structures forced by earthquake induced ground motion. To this aim it is proposed for the first time to exploit the structure-soil-structure mechanism to develop a device, hosted in the soil but detached from the structure, able to absorb part of the seismic energy so to reduce the vibration of neighbourhood structures. The design of the device is herein addressed to protect monopile structures from earthquake induced ground motion. By modelling the ground motion as zero-mean quasi-stationary response-spectrum-compatible Gaussian stochastic process, the soil as visco-elastic medium and the target monopiled-structure as a linear behaving structure the device, herein called Vibrating Barrier (ViBa), has been designed through an optimization procedure. Various numerical and experimental results are produced to show the effectiveness of the ViBa. Remarkably, a significant reduction of the structural response up to 44% has been achieved.

“…To reach this objective, a simple case study is first performed in order to best characterize the Structure-Sol-Structure interaction. The numerical model chosen corresponds to the "Soil-Struction Interaction NUPEC" workshop organized in Japan NUPEC (NUclear Power Electric Corporation [4]). Indeed, NUPEC had set up a large experimental program to study this type of phenomenon by building a small scale buildings in areas of high seismicity.…”

Abstract.This work aims to study the influence of the Structure-Soil-Structure Interaction (SSSI) on the seismic response of structures. It focuses on the characterization of the main factors influencing this phenomenon by studying the well-known and documented case NUPEC from 90s and by conducting different case scenarios with a linear model. The performed numerical simulations are able to capture the influence of the adjacent structure, which partly depends on the type of foundation soil. A parametric analysis was also performed to highlight the influence of some parameters (such as a distance between building, mass, height and embedded depth) on the response of the main structure.
