This paper is divided into two parts. The first part presents recent measurements of ground motion in the LHC tunnel at CERN. From these measurements, an update of the ground motion model currently used in accelerator simulations is presented. It contains new features like a model of the lateral motion and the technical noise. In the second part, it is shown how this model can be used to evaluate the seismic response of a linear accelerator in the frequency domain. Then, the approach is validated numerically on a regular lattice, taking the dynamic behavior of the machine alignment stage and the mechanical stabilization of the quadrupoles into account.

“…Der Kiureghian (1996) pointed out that, for multiply supported structures located in regions with rapidly varying local soil properties, the effect of site response can be more signifi cant if the structure has important modes within the range of 0.5-1.5 Hz. Meanwhile, related studies have also shown the importance of the site-response effect to dynamic responses of structures (Der Kiureghian and Neuenhofer, 1992;Dumanogluid and Solyluk, 2003;Zhang et al, 2009;Bilici et al, 2009). Therefore, in some conditions, the site-response effect should also be taken into account in the simulation of spatially correlated ground motions.…”

“…However, the spatial variation of seismic ground motions has an important effect on the response of extended structures, such as dams, bridges and pipelines, and has been studied by many researchers. Most research is focused on stochastic methods in the frequency domain (Chen and Harichandran, 2001;Zanardo et al, 2002;Liao and Li, 2002;Dumanogluid and Solyluk, 2003;Zhang et al, 2009;Bilici et al, 2009). Meanwhile, several response spectrum methods that take into account the effect of correlated ground motion have been developed (Yamamura and Tanaka, 1990;Berrah and Kausel, 1992;Der Kiureghian and Neuenhofer, 1992).…”

A new model to simulate spatially correlated earthquake ground motions is developed. In the model, the main factors that characterize three distinct effects of spatial variability, namely, the incoherency effect, the wave-passage effect and the site-response effect, are taken into account, and corresponding terms/parameters are incorporated into the well known model of uniform ground motions. Some of these terms/parameters can be determined by the root operation, and others can be calculated directly. The proposed model is fi rst verifi ed theoretically, and examples of ground motion simulations are provided as a further illustration. It is proven that the ensemble expected value and the ensemble auto-/cross-spectral density functions of the simulated ground motions are identical to the target spectral density functions. The proposed model can also be used to simulate other correlated stochastic processes, such as wave and wind loads.

“…Several methods exist, including finite element (FE) [Demirel, 2015] and boundary element (BE) approaches or coupled BE-FE [Antes and Von-Estorff, 1987;Yazdchi et al, 1999]. The reservoir can be discretized using elastic "solid finite elements" [Wilson, 1975;Zienkiewicz et al, 1986;Wilson, 1995;Dakoulas and Gazetas, 2008;Pelecanos et al, 2013] in which the bulk modulus of the water is assigned to the elements with a very small shear modulus, or "fluid elements", following Eulerian [Kucukarslan et al, 2005;Gogoi and Maity, 2007;Fan and Li, 2008] or Lagrangian [Akkose et al, 2008;Bilici et al, 2009;Kartal and Bayraktar, 2013] or MPM [Kularathna and Soga, 2017a; …”

The objective of this study is to investigate the effects of damreservoir interaction (DRI) on the nonlinear seismic response of earth dams. Although DRI effects have for long been considered as insignificant for earth dams, that conclusion was mainly based on linear elastic investigations which focused only on the acceleration response of the crest without examining the seismic shear stresses and strains within the dam body. The present study explores further the impact of DRI focusing on the nonlinear behavior of earth dams. The effects of reservoir hydrodynamic pressures are investigated in terms of both seismic dam accelerations and nonlinear dynamic soil behavior (seismic shear stresses and strains). It is shown that although dam crest accelerations are indeed insensitive to DRI, the stress and strain development within the dam body can be significantly underestimated if DRI is ignored.
