ABSTRACT: THE ARTICLE PRESENTS THE DETERMINATION OF THE DYNAMIC RESPONSE OF A RIGID STRIP FOOTING BONDED TO A VISCOELASTIC HALF-SPACE USING AN INDIRECT BEM FORMULATION WITH VARIOUS INTERFACE TRACTION INTERPOLATION MODELS. NON SINGULAR CONSTANT LINEAR, QUADRATIC AND SPLINE INTERPOLATION MODELS AND SINGULAR LINEAR AND SPLINE INTERPOLATION MODELS ARE USED. RESULTING INTERFACE TRACTION DISTRIBUTION AND ROTATION OF THE FOUNDATION SUBJECTED TO A ROCKING MOMENT ARE PRESENTED AND ANALYZED. THE NUMERIC RESULTS SHOW THAT THE SINGULAR MODELS PROVIDE MUCH SMOOTHER TRACTION DISTRIBUTION AND BETTER CONVERGENCE RATES FOR THE FOUNDATION ROTATION.
KEYWORDS: ELASTODYNAMICS, BOUNDARY ELEMENT METHOD, SOIL-STRUCTURE INTERACTION, SINGULAR FUNCTIONS, SPLINES.
