CHARACTERISTICS OF LOCAL SITE EFFECTS ON SEISMIC MOTION - NON-LINEARITY OF SOIL AND GEOLOGICAL IRREGULARITY

To determine seismic ground motion for a seismic design, it is necessary to take site effects into account, such as nonlinearity of soil and geological irregularities. This paper discusses two aspects of site effects. One is the estimation of nonlinear earthquake response of soil deposits, and the other the estimation of seismic motion on the ground that has topographical and geological irregularities. A new stress-strain model is proposed that is applicable to earthquake response analyses of soil deposits under large earthquakes. Next, a practical method is developed to evaluate amplification characteristics of ground motion on the irregularly layered ground.
