Self-study notes - BASIC DYNAMICS OF STRUCTURES

The mass of the structure is 5000 kg and is concentrated on the beam that is assumed to be rigid. The two columns are assumed to be mass-less and each has a flexural stiffness (EI) of 4.5x106 Nm2. If the structure has a damping ratio (ζ) of 4% (=0.04), calculate; (a) the undamped natural frequency and (b) the damped natural frequency. ................
