NONLINEAR RESPONSE ANALYSIS OF GROUND BY PSEUDO-SPECTRAL METHOD
|
´˜^i‰pjF |
A new method for analyzing non-linear earthquake response of ground was developed using a one-dimensional pseudo-spectral method. It incorporates the non-linear relations between stress and strain into the time-domain calculations of earthquake motions. The method exactly follows the time variations of strains in terms of the time-varying rigidities and damping factors of soils, providing a quite different technique from conventional methods such as the equivalent linear method. We applied it to the down-hole records obtained at Port Island during the 1995 Hyogoken-Nanbu Earthquake to confirm its availability.
