Exact dynamic member stiffnesses for a beam on an elastic foundation |
|
| Authors: | F W Williams D Kennedy |
| Abstract: | This paper gives exact Bernoulli–Euler dynamic flexural member equations for a uniform beam on an elastic foundation. These enable exact results to be obtained when the beam is included in free or sinusoidally forced vibration calculations for a plane or space frame, at any frequency. In addition, information is presented to ensure that no natural frequencies are missed in a free vibration analysis. |
