CURVOGRAMS OF STRONG EARTHQUAKE GROUND MOTION

The analyses of the effects of strong earthquake shaking on engineering structures are discussed. This technical note reports a study which considered a case in which the ground waves have wave lengths at least 2-3 times longer than the structural dimensions (but are too short to ignore the resulting pseudostatic deformations) of the foundation system during the wave passage. A figure is used to illustrate a plan view of a rectangular foundation deformed into bending by the passing ground wave. Since the significance of such deformation for structural response can be evaluated with sufficient accuracy if the radius of curvature of ground deformation is known, a method for evaluating the curvograms on ground surface is presented.
