摘要
在结构动力分析中,常采用振型叠加法,当略去高阶振型的影响或当自由度与质量不对应时造成一定的误差,对此,本文讨论一种修正的方法.
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.
