Numerical simulation of dynamic soil–structure interaction in shaking table testing

A shaking table real-time substructure experiment of an equipment–structure–soil interaction system

“…Accounting for deformation of soil and foundation, full-coupled soilstructure shaking table tests [5][6][7][8] and numerical analysis [9][10][11][12] were conducted and gained deeper insight into the seismic performance of structures. With soil intervention, vibration period of the whole model extends and thus influences authentic seismic responses of superstructures.…”

Large Scale Soil-Foundation-Structure Model in Greece: Dynamic Tests vs Fem Simulation

“…Soil-structure interaction (SSI) has been widely investigated since the 1970s by means of theoretical approaches [1,2,3], field and laboratory studies as well as numerical modelling [4,5,6,7,8,9,10,11,12,13].…”

“…As for field and laboratory studies, SSI phenomena are commonly studied in small-scale by implementing experiments in shaking-table or centrifuge apparatuses [14,10,11,15,16]. Laboratory studies are particularly invaluable for the known initial and boundary conditions, and for the large quantity of applied instrumentations.…”

Time-Domain Soil-Structure Interaction Analysis of Nuclear Facilities

“…The assumption of equivalent linear behavior does not explicitly consider the nonlinear behavior of soil-structure systems such as the hysteretic behavior of soil. In the time domain analysis method [2][3][4][5][6] , the dynamic analysis is carried out by solving the equation of motion at each time step using a direct numerical integration scheme. In this approach, a large soil domain and a structural system is modeled as a single numerical model such that the inertial and kinematic interactions are inherently considered in the analysis.…”
