Unformatted text preview: .(8) : (8) leads to: (20) And transforming to : (21) The term [KF]{XFq} is called "Driving Force Vector". There are a few textbooks on the soil structure interaction: in which the explanation of SSI begins with Eq.(21): (21) Getting back to Eq.(13): (13) The dynamics of Eq.(13) can be explained by Fig.7: When the soil has the void, the stresses along the F must disappear. The displacement vectors {{XFq} {XSq}}T are the earthquake response displacements of the soil with the void, and it is slightly difficult to compute them. Consider the soil before the excavation as shown in Fig.8: where the void is occupied with the soil. The soil without the void becomes a layered soil media without the geometrical irregularity. When the earthquake disturbance is the incident SH wave, the earthquake response analysis of this type of the soil can be done easily by the one dimensional shear wave propagation theory ( a computer code "SHAKE"). After the earthquake response analysis of the soil shown in Fig.8...
