Evaluation of Floor Vibration Existing in Apartment Building

In recent years building floors become larger and more spacious due to the development of new design methods and high strength and light weight materials, However, such long span floor systems may provide smaller amount of damping and have longer period so that they would be more vulnerable to the floor vibration. This study attempts to evaluate the performance of the floors in typical apartment buildings. Three different floors with the area of $43.2m^2 41.44m^2 and 34.5m^2$, were investigated. The guideline provided by AISC(1997) is used to check the acceptability of the floor vibration.
