摘要
非比例阻尼问题，在结构动力分析中普遍存在。本文应用子空间Ｒｉｕｚ向量叠加方法。
The non -proportinal damping problem generally exsts in dynamic analysis ofstructures.In this paper, solving the problem by a subspace RitZ vectors superposition methodeffectively reduced the work load of calculation, and improved the precision of calculation.
