Seismic site period studies for nonlinear soil in the city of Ottawa, Canada

TL;DR: In this article, site period maps at various strain levels were developed for the combined cities of Ottawa and Gatineau in eastern Ontario and western Quebec in order to support earthquake response studies in areas containing postglacial, soft, silty-clayey sediments, which comprise 60% of the urban areas.

New p-y model for seismic loading prediction of pile foundations in non-liquefiable and liquefiable soils considering modulus reduction and damping curves

TL;DR: In this paper , a new p-y model is proposed for the seismic loading prediction of pile foundations using the Beam on Nonlinear Winkler Foundation (BNWF) method, which matches the desired modulus reduction curve by identifying three parameters in a hyperbolic function and a linear function using a GA, and the desired damping curve by applying the Ishihara-Yoshida rule that controls the unloading-reloading curves iteratively through the three parameters.

Analysis of Seismic Fragility Functions of Highway Embankments

TL;DR: In this article, the seismic fragility functions of a highway embankment were defined following an analytical methodology, and the relationship between displacements and different seismic intensity measures (PGA, Arias-intensity) was investigated.

Evaluation of a simplified soil constitutive model considering implied strength and pore-water pressure generation for one-dimensional (1D) seismic site response

TL;DR: In this paper, the authors evaluated the impact of PWP generation on soil softening and liquefaction of sandy soils during earthquakes, with potential influence on site response and seismic design.

Moduli and Damping Factors for Dynamic Analyses of Cohesionless Soils

TL;DR: In this article, a simple relationship is proposed to relate the shear modulus of a cohesionless soil to a modulus stiffness coefficient, which is a soil property and depends on the characteristics of the soil, and the effective mean principal stress at any point in the soil.
