For buildings where users or equipment are sensitive to movements tight vibration criteria are appropriate.
Concrete floor vibration.
However there can be situations where the effects of vibration are one of the main design issues that need to be addressed.
We would like to show you a description here but the site won t allow us.
It is generally perceived that vibration is not an issue for reinforced concrete floor systems.
The construction of lighter and longer floor structures in recent years has resulted in an increasing incidence of floor vibration.
Concrete floating floors are used for many purposes.
Vibration isolation buildings are unavoidably near busy streets trains and subways even though they contain space that must be vibration free an.
In conventional steel concrete floor systems the fundamental frequency may be estimated by using engineering.
Floor vibrations are generally caused by dynamic loads applied either directly to the floor by people or machinery or indirectly by moving floor supports after transmission through the building structure or through the ground.
Because of the inherent mass and stiffness of such systems this perception is generally true.
