摘要
介绍了利用随机扩阶系统方法求结构固有频率均值的方法,通过具体算例,证明了该算法的精确和实用性,对于正确估计结构设计的可靠性具有重要意义。
The method utilizing the stochastic systemorder expansion method to determine the mean value of natural frequency of stochastic structure is introduced. Combined with example the accuracy and practicability of this algorithm are demonstrated. This method plays significant role in estimating the reliability of structural design.
