【Abstract】 In the dynamical analysis of structure, we often adopt the super position method of vibrational modes. When the response of higher order vibrational modes have been ignored, or the degree freedom is not identical with the mass, it could be result in error. For this reason, this paper gives out the method of corrected calculation.更多还原
