Abstract

Consideration is given to the effect of soil cross-anisotropy on the dynamic displacement functions of a rigid strip surface foundation subjected to vertical or horizontal forces and moments that vary harmonically with time and are distributed uniformly across the longitudinal axis so that plane strain conditions prevail. The results are obtained using an analytical-numerical formulation which models realistically the rough soil-foundation interface, properly accounts for phenomena associated with propagation of waves emanating from the foundation and considers linear hysteretic material damping in the soil. Particular emphasis is accorded to the sensitivity of the calculated frequency-dependent foundation displacements to the assumed values of the anisotropic soil constants, appropriate for drained loading conditions.

Importance of Soil Anisotropy on Foundation Displacement Functions

St. Louis, Missouri

Consideration is given to the effect of soil cross-anisotropy on the dynamic displacement functions of a rigid strip surface foundation subjected to vertical or horizontal forces and moments that vary harmonically with time and are distributed uniformly across the longitudinal axis so that plane strain conditions prevail. The results are obtained using an analytical-numerical formulation which models realistically the rough soil-foundation interface, properly accounts for phenomena associated with propagation of waves emanating from the foundation and considers linear hysteretic material damping in the soil. Particular emphasis is accorded to the sensitivity of the calculated frequency-dependent foundation displacements to the assumed values of the anisotropic soil constants, appropriate for drained loading conditions.
