A note on rotational components of earthquake motions on ground surface for incident body waves

Trifunac, M.D.

Abstract This paper shows that the Fourier amplitude spectra of rocking and torsional components of strong shaking on ground surface can be derived exactly in terms of (1) wavelength of incident waves, (2) Fourier amplitude spectra of vertical (for incident $P$ and $SV$ waves) or horizontal (for incident $SH$ waves) ground motion, and (3) the angle of incidence of plane body waves, $θ 0$ . Application of these results in earthquake engineering is discussed.
