On the Flexural-Torsional Vibration and Stability of Beams Subjected to Axial Load and End Moment

Table 4

Fundamental frequencies for pinned-pinned boundary condition (P-P), when force and end moment are applied; a 40-element FEM model is used.

	0	6.14	9.21
Force (MN)	FEM fundamental frequency (Hz)
0	7.175	6.947	6.651
0.62	7.440	7.220	6.935
1.23	7.695	7.483	7.208
1.85	7.942	7.736	7.471
