Lecture 31 : Basics of soil dynamics [ Section 31.2 :
Different modes of vibration; Undamped ]
Undamped free vibration :
Free vibrations means the structure is disturbed from equilibrium and then vibrates without any applied forces. The damping forces cause the dissipation of the motion. It is undamped i.e. the coefficient of damping “c”=0. This system is also called as a Single Degree Of Freedom system.(SDOF).
