During past earthquakes, the ground motions on soft soil sites were found to be generally larger
than those of nearby rock outcrops, depending on local soil conditions (e.g., Seed and Idriss,
1968). These amplifications of soil site responses were simulated using several computer
programs that assume simplified soil deposit conditions such as horizontal soil layers of infinite
extent. One of the first computer programs developed for this purpose was SHAKE (Schnabel et
al., 1972). More than 25 years after its release, SHAKE is still commonly used and referenced
computer programs in geotechnical earthquake engineering.
SHAKE computes the response in a
horizontally layered soil-rock system subjected to transient and vertical travelling shear waves.
SHAKE is based on the wave propagation solutions of Kanai (1951), Roesset and Whitman
(1969), and Tsai and Housner (1970).
