| Abstract: | This paper used a method of curvature circle replacing general curve,the authors obtain twouniversal formulas calculating the inherent frequency of relative oscillation in miniamplitude be-tween columns that have general section curve.The formulas are simple,By means of the formu-las,not only judging whether or not two columns have stable relative oscillation but also calculateinherent frequency of socillation in miniamplitude is simple. |
