COMPREHENSIVE STUDY ON EARTHQUAKE RESPONSE ANALYSIS OF GROUND -FREQUENCY DEPENDENT EQUIVALENT STRAIN FOR EQUI-LINEARIZED TECHNIQUE

抄録（英）：
A method is presented for equi-linearized seismic response analysis of multi-layered ground including frequency-dependent effect of shear modulus and damping on ground motion amplification. The frequency-dependent equivalent strain in proportion to the Fourier amplitude of shear strain tine history is defined for evaluation of equivalent shear modulus and damping factor depending on the frequency contents. The method is examined in the strong motion array records with minutely serveyed soil profile at array observation station lacated at very soft ground. Superiority of the presented method to the conventional equi-linearized method is demonstrated especially in case of strong level of input ground motion.
