Problem:
1. Using the Finite Element method calculate the first 6 natural frequencies for the simply supported beam, Figure 1. Use UB 254 x146 x 37 from the attached list.
E = 200 GPa, p=7830 kg/m3

2. Using ANSYS finite element code to calculate the first 6 natural frequencies for the frame Figure 2 by using
1. bar elements
2. beam elements
Analyse the results.
Apply load F = 40 kN at point C and do harmonic analysis of the frame with damping (0, 1%, 5%, and 10%).
Analyse the results.
