Structural Dynamics Notes VTU

Hii sir, I wants to get the Notes of the Subject Structural Dynamics of the BE Electronic Engineering of the VTU University ?

[shikha]

As you Asking for the Notes of the Subject Structural Dynamics of the BE Electronic Engineering of the VTU University the Syllabus is As Follow

Basics
Real-life structures are subjected to loads which vary with time.

Except self weight of the structure, all other loads vary with time. In many cases, this variation of the load is small, hence static analysis is sufficient

However, in case of offshore structures (oil rigs), high rise buildings subjected to lateral loads (wind, earth quake)dynamic effects of the load must be explored for knowing the exact safety and reliability of The structure.

Some Definitions:

Vibration and oscillation: If motion of the structure is oscillating (pendulum) or reciprocatoryalong with deformation of the structure, it is termed as VIBRATION. In case there is no Deformation which implies only rigid body motion, it is termed as OSCILLATION.

Free vibration:
Vibration of a system which is initiated by a force which is subsequently withdrawn. Hence this vibration occurs without the external force.

Forced Vibration:
If the external force is also involved during vibration, then it is forced vibration.


Damping: All real life structures, when subjected to vibration resist it. Due to this the amplitude of the vibration gradually, reduces with respect to time. In case of free vibration, the motion is damped out eventually.
