Unformatted text preview: he massless rigid foundation. The dynamic Impedance Function equals to the inverse of the response of the massless rigid foundation when unit force vector is applied. The Foundation Input Motion equals to the response of the massless rigid foundation when the earthquake disturbance is applied. (8) The natural frequency of the building is different from the fixed base natural frequency. (9) Larger damping factor is given by SSI. The damping factor of the coupling system is much larger than that of building itself. (10) This tendencies of (8) and (9) becomes more remarkable in lower rise or stiffer building on weaker soil.
