Human-Induced Floor Vibrations – Controlling the Bounce

Human-Induced Floor Vibrations – Controlling the Bounce

Abstract

Structural floor vibrations can affect the performance of buildings in many ways depending upon the use of the space and the magnitude of the vibrations.  Excessive vibration can disrupt the function of sensitive equipment, affect human comfort, and, in extreme cases, even cause panic.  On elevated floors and pedestrian bridges, human activity (e.g., walking, running, dancing, and aerobics) is often the dominant source of vibration.  Since addressing these issues in design, rather than mitigating after they have been noticed as a problem, is much easier and cost effective, it is important to recognize when they might arise.  This presentation outlines common situations in which vibration should be carefully considered with examples from real-world projects ranging from high-end research facilities, to unique retail and office situations, to event spaces and pedestrian bridges.  The presentation discusses how the human-induced vibrations are predicted using advanced analytical tools, and how vibrations can be mitigated to achieve the target criteria.

Learning Objectives:

  1. Develop an awareness of the dynamic properties affecting floor vibration.
  2. Describe how floor vibrations can affect different types of occupancies and spaces.
  3. Understand how human-induced floor vibrations are predicted.
  4. Understand how human-induced floor vibrations are mitigated
