28. Because of the short wavelength, there is a pronounced rotational component of the ground motion in this frequency range. In fact, other than the horizontal translations due to the horizontal component of ground motion, the most significant contributor to displacements at the top of the structure appears to be the rotational component 30 ! 4 Hz FIGURE 25. Idealiied planar model of the periscope auperatructure and the fundamental mode of vibration. of the ground motion. Another way of looking at this is that the assumption of uniform support motion is quite invalid since the motion of the soil mass across the foundation mat varies greatly.
