摘要
本文从矩阵理论出发,介绍了对自振频率进行验证的实用方法。文后,给 出了我国最大跨径刚构桥的有关计算过程。
In this paper, a feasible method about verifying the natural frequencies of the structure is introduced based on the matrix theory. Moreover, the author points out that the verifying method is simple and quick to calculate the eigenvalues of the great complex structure. As an example, the calculating process of the longest span frame bridge in our country is introduced in the end.
