ABSTRACT
In the discontinuous models as DDA and NMM, the earthquake wave is propagating from the base block to the upper blocks by the friction between blocks in theoretical. The experiments of response on the artificial structure models has been applied by prescribed displacement on the actuator of excitation apparatus. The authors report some factors in earthquake motions affects in modeling described above for the discontinuous models by using 4-node iso-parametric NMM (Sasaki & Ohnishi, 2001) and 3D-DDA (Shi, 2001).
