A one-storey building is subjected to a free-vibration test. During the test, it was observed that 300 kN force was required to displace the roof of the structure by 5 mm. After the instantaneous release of the force, the maximum displacement at the return swing was 6 mm, and it took 2.0 sec after. Compute: (a) Effective stiffness and mass of the structure (b) Frequency of vibration; and (c) Damping Coefficient.

Pick up the correct statements about Free Vibration of Undamped SDOF System: Motions taking place with the applied force set to zero are called free vibrations. Correct Option Correct Option When applied force is zero and there is no damping in the system then the SDOF system is governed only by the influence of the initial conditions. In an undamped system under free vibration, the equation of motion is given mä + kx = 0, wherek is Correct Option stiffness of the SDOF System. D The solution to mä + kx = 0 represents a simple harmonic motion. Correct Option
