Steady state harmonic response of nonlinear soil-structure interaction problems is addressed in this paper. Due to well-known stiffness degradation phenomenon, the steady-state study referred small-medium strain condition whereas no significant pore water pressure change observed (e.g. clayey soils and sands drained conditions). A novel cyclic hysteretic model based on Preisach formalism propos...

Parallel analyses about the dynamic responses of a large-scale water conveyance tunnel under seismic excitation are presented in this paper. A full three-dimensional numerical model considering the water-tunnel-soil coupling is established and adopted to investigate the tunnel’s dynamic responses. The movement and sloshing of the internal water are simulated using the multi-material Arbitrary L...

in this study, the effective parameters on the inelastic response of asymmetric buildings is evaluated for an ensemble of real iranian earthquake records by considering soil-structure interaction. then, the design eccentricity obtained from the inelastic dynamic soil-structure analysis is compared with the design eccentricity of seisimic codes of iran, atc-3, new zeland, canada, mexico, austral...

Based on an actual corrugated steel plate arch bridge, considering soil-structure interaction, by using the finite element program of ANSYS, a 2-D finite element model was set up to analyze the soil pressure and structural deformation under different load conditions in detail. Since this type of structure relies on the soil-structure interaction to share the load, as the structural parameters h...

The influence of soil-structure interaction in the analysis and design of a 6-storey and basement reinforced concrete frame building is investigated. Models simulating two different conditions: namely soil-structure interaction, and fixed-base behavior are considered. The influence of the soil structure interaction in the dynamic behavior of the structure is reflected in an increase in the vibr...
