This paper present a method for synthesizing the structural modification in problems concerning compliance shift on the Bode diagram by use of the finite element sensitivity analysis. The basic notion employed is to search for the objective design in the vicinity of the baseline design. The constraint intensity and damping are adopted as design variables. The shift syntheses of the compliance transfer function is carried out numerically by means of setting several target frequencies on the Bode diagram in regard to the vibration of a straight pipe and a doubly bent pipe with Rayleigh damping. The numerical examples verify that the shift synthesis can be completed by a small number of iterations, usually less than ten.
