Sample CE6701 Structural Dynamics and Earthquake Engineering Important Questions:
1. What is mean by Vibration?
Any motion which repeats itself after an interval of time is called vibration or oscillation.
2. What is the formula for free vibration response?
The corresponding equation under free vibrations can be obtained by substituting the right hand side of equation as zero. This gives
mu + Cu +Ku = 0
3. What are the effects of vibration? (CE6701 Structural Dynamics and Earthquake Engineering Important Questions)
i. Effect on Human Sensitivity.
ii. Effect on Structural Damage.
4. What is mean by theory of vibration?
Vibration is the motion of a particle or a body or a system of concentrated bodies having been displaced form a position of equilibrium, appearing as an oscillation. Vibration was recognized in mechanical systems first and hence the study of vibrations fell into the heading “Mechanical Vibrations” as early about 4700 years ago.
5. Define damping.
Damping is a measure of energy dissipation in a vibrating system. The dissipating mechanism may be of the frictional form or viscous form. In the former case, it is called dry friction or column damping and in the latter case it is called viscous damping. Damping in a structural system generally assumed to be of viscous type for mathematical convenience. Viscous damped force (Fd) is proportional to the velocity (?̇) of a vibrating body. The constant of proportionality is called the damping constant (C). Its units are NS/m.
6. What do you mean by Dynamic Response? (CE6701 Structural Dynamics and Earthquake Engineering Important Questions)
The Dynamic may be defined simply as time varying. Dynamic load is therefore any load which varies in its magnitude, direction or both, with time. The structural response (i.e., resulting displacements and
stresses) to a dynamic load is also time varying or dynamic in nature. Hence it is called dynamic response.
