The aim of this paper is to study the effects of Soil-Structure Interaction (SSI) on the seismic response of coupled wall-frame structures on pile foundations considering the non-linear behaviour of the superstructure. According to the substructure method, the kinematic interaction analysis is performed by means of a numerical procedure obtaining the dynamic impedance functions and the foundati...

This paper proposes an analytical method based on drained solutions of cavity expansion and contraction in a unified clay sand model to investigate tunnel–soil–pile interactions. Cavity analyses are used evaluate the effects pile installation ground stresses determine end-bearing capacity distribution shaft friction. methods were adopted replicate tunnel convergence–confinement response using s...

A Boundary Element Method (BEM) approach was developed for the analysis of pile groups. The proposed method includes: the non-linear behavior of the soil by a hyperbolic modulus reduction curve; the non-linear response of reinforced concrete pile sections, also taking into account the influence of tension stiffening; the influence of suction by increasing the stiffness of shallow portions of so...

The liquefaction of soil surrounding a pile significantly affects the dynamic interaction between and pile. In particular, sloping ground can induce permanent deformation bending moment on due to lateral displacement liquefied in downslope direction. However, numerical analysis studies piles installed liquefiable slope have been very limited not properly simulated behavior Therefore, modified s...

A p-y curve method of pile near cohesionless soil slope under reversed lateral load is proposed. This takes into account the failure mode around and interaction between soil, derives ultimate resistance pile. Considering change original stress state due to deflection foundation, influence relative density, initial mean effective foundation on internal friction angle sand evaluated further accur...

To deal with the uncertainties in modeling offshore wind turbines, we propose a parameter inversion method for pile–soil interaction model based on structural health monitoring results and numerical model. The proposed has model, an objective function selected using both identified results, inverse optimization random search algorithm assumed space. minimum are as situ parameter. is confirmed t...
