displacements they used the abacus in Figure 10.6 proposed by Ambraseys and
Menu [AMB 88b], which gives the displacements relative to the velocity

given by
the accelerograph applied at the base of the dam function of

. The abacus is
applicable to earthquakes of magnitudes between 6.55 and 8.25.

Displacements versus accelerations [AMB 88b]
Figure 10.7 gives measured mean values for dams with heights between 30 and
180 m, and shear wave velocities between 92 and 300 m/s.
