摘要：

The vibration of a Bernoulli-Euler beam considering eccentric axial force is investigated; the closed-formed dynamic stiffness matrix which includes the contribution of eccentric axial force is derived through the governing differential equation. The well-established Wittrick-Williams algorithm is implemented to calculate the beam natural frequencies iteratively. The calculated dynamic characteristics from the proposed method are compared to those analytic solutions. A good agreement is achieved.
