Three-dimensional numerical analysis on seismic behavior of soil-piled raft-structure system

Influence of Soil-Structure Interaction on Seismic Response of Multi-Storey Buildings

“…In the current study, Mohr-Coulomb model has been adopted as the constitutive model to simulate nonlinear behavior of the soil medium. Mohr-Coulomb model has been adopted in various studies to simulate nonlinear behavior of soils with values of cohesion [5,[11][12][13][14] in soil-structure interaction problems. Although other advanced soil plasticity models are available but the application of such models may create complexity in dynamic analysis.…”

“…Although other advanced soil plasticity models are available but the application of such models may create complexity in dynamic analysis. Therefore, the Mohr-Coulomb model is employed in this study to achieve a balance between the analysis accuracy, and cost [14]. Mohr-Coulomb model is an elastic-perfectly plastic model.…”

“…Ramadan et al [4] used analytical methods to investigate the seismic soil-structure interaction (SSI) effects on the structural response. Two-dimensional models of moment-resisting frames with variable heights (7,10,14, and 18 floors) are analyzed using OPENSEES program. The results showed that ignoring SSI results in underestimation of the fundamental period and overestimation of base shear forces of the analyzed structures.…”

Effect of soil-pile-structure interaction on seismic behaviour of nuclear power station via shaking table tests

“…For example, Mostafa and EI Naggar [14] proposed a method to analyse the dynamic lateral response of pile group under harmonic excitation. Basack and Nimbalkar [15] developed a numerical model based on a two-dimensional (2D) dynamic finite-element (FE) approach.. For cases when superstructures were considered, the seismic response of the pile-soil-structure interaction were studied experimental [16][17][18][19] and numerically [20][21][22][23][24][25]. As n-g centrifuge experiment, liquefication study and numerical simulation beyond the scope of this paper, so they are not discussed in this paper.…”
