“…It appears that the lateral tanks act like a tuned mass damper for the central tank. Similar observations have been made for adjacent buildings by using discrete models . However, it should be expected that inclusion of material damping for the soil in the analysis diminishes to some extent this ‘destructive’ interference of the modes.…”

Summary A refined substructure technique in the frequency domain is developed, which permits consideration of the interaction effects among adjacent containers through the supporting deformable soil medium. The tank‐liquid systems are represented by means of mechanical models, whereas discrete springs and dashpots stand for the soil beneath the foundations. The proposed model is employed to assess the responses of adjacent circular, cylindrical tanks for harmonic and seismic excitations over wide range of tank proportions and soil conditions. The influence of the number, spatial arrangement of the containers and their distance on the overall system's behavior is addressed. The results indicate that the cross‐interaction effects can substantially alter the impulsive components of response of each individual element in a tank farm. The degree of this impact is primarily controlled by the tank proportions and the proximity of the predominant natural frequencies of the shell‐liquid‐soil systems and the input seismic motion. The group effects should be not a priori disregarded, unless the tanks are founded on shallow soil deposit overlying very stiff material or bedrock. Copyright © 2016 John Wiley & Sons, Ltd.

This paper evaluates the effect of Structure-soil-structure interaction (SSSI) between two buildings given different parameters of the buildings, inter-building spacing, and soil type. A two-dimensional simple discrete nonlinear model is proposed that is described by a set of nonlinear differential equations of motion. A nonlinear phenomenological Bouc-Wen model, for the soil directly underneath the foundations, linear rotational interaction spring between buildings and linear behaviour of buildings are assumed. The seismic ground motion employed is spectrally matched with EC8 elastic spectra. The results showed that there are both unfavourable and beneficial configurations of the two buildings that produce important differences between nonlinear SSSI and nonlinear SSI (the uncoupled building case). Importantly it is demonstrated that the adverse effects of SSSI can be more pronounced when the nonlinear soil behaviour is assumed.

“…During the last two decades, several authors highlighted the effects of the structure-soil-structure interaction by means of studies on the site-city interaction [5][6][7]. Recently, Alexander et al [8] developed a discrete model to study the SSSI problem of surface foundations by considering stochastic ground motion excitation and, Aldaikh et al [9] extended the work of Alexander et al [8] to the case of three buildings with validation of the discrete theoretical model by means of experimentally shaketable testing.…”

A novel device, called vibrating barrier (ViBa), that aims to reduce the vibrations of adjacent structures subjected to ground motion waves has been recently proposed. The ViBa is a structure buried in the soil and detached from surrounding buildings that is able to absorb a significant portion of the dynamic energy arising from the ground motion. The working principle exploits the dynamic interaction among vibrating structures due to the propagation of waves through the soil, namely the structure-soil-structure interaction. In this paper the efficiency of the ViBa is investigated to control the vibrations of a cluster of buildings. To this aim a discrete model of structures-site interaction involving multiple buildings and the ViBa is developed. In particular, the effects of the soil on the structures, i.e. the soil-structure interaction (SSI) as well as the structure-soilstructure interaction (SSSI) and the ViBa-soil-structures interaction are taken into account in this paper by means of linear elastic springs as in the conventional Winkler approach for a linear elastic soil medium.Closed-form solutions are derived to design the ViBa in the case of harmonic excitation from the analysis of discrete models. Advanced Finite Element numerical simulations are performing in order to assess the efficiency of the ViBa in protecting one or more buildings. Parametric studies are also conducted to identify beneficial/adverse effects in the use of the proposed vibration control strategy to protect cluster of buildings.
