摘要：

A fundamental but reliable and comprehensive approach of obtaining the exact roots for the frequency equation of given beam systems is presented. The frequency equation is incorporated with the boundary conditions, which depend on the physical components attached to the beam's ends. The eigenvalues are evaluated without knowing the explicit form of the frequency equation. The validity of the proposed algorithm is confirmed by considering an illustrated model with three case studies.
