Floor Serviceability Under Dynamic Loading

Abstract
Some structures such as floors and tall buildings that meet the code design
criteria exhibit unacceptable vibrations relative to the human user. In particular,
occupants of long-span floors constructed with open-web joists and light-weight
concrete are likely to experience perceptible or annoying vibrations due to
normal human activity that is characterized by impact, such as walking, dancing,
running, and jumping. Thus, it is important that a serviceability criterion based
on human response be used at the design stage to avoid costly problems after the
floor is constructed and put into service. Note that human response to vibration
is a function of the human body characteristics, the intensity and type of the
loading, and the characteristics of the structure such as its frequency, stiffness,
mass, and damping. In this paper, a serviceability criterion based on the humanload-
