STRONG MOTION SIMULATION USING BOTH NONLINEAR PARAMETERS AND EFFECTIVE STRESS ANALYSIS

Abstract

In conventional papers, the author pointed out the importance of the role of multiple nonlinear effects in strong motion prediction and proposed a simple method to take into account the effects by correcting empirical Green's functions using “nonlinear parameters”. In the present article, it is proposed that the method using nonlinear parameters should be convined with conventional effective stress analysis to consider the effects of soil nonlinearity more appropriately. The convined method is applied to strong motion records from the 1995 Hyogo-ken Nanbu (Kobe) and the 1993 Kushiro-oki earthquakes and its validity is investigated.
