Brad is a vibration and acoustics specialist, with a special interest in vibration control related to structural systems. He has 15+ years of experience solving complex vibration and acoustic problems.  During his career he has worked on hundreds of high profile projects throughout the world and has been actively involved in vibration design for high rise, health care and laboratory facilities, as well as long-span highway and pedestrian bridges.  His experience also includes wind-tunnel testing and damper design for buildings and bridges.

The densification of urban education and healthcare campuses is driving the development of taller buildings that house continuously evolving technologies and treatments. A by-product of ‘building up’ is challenges with co-location of incompatible spaces from a noise and vibration perspective. Some increasingly common examples include mid-level mechanical floors stacked above/below acoustically-sensitive areas; vibration-sensitive research and medical tools above ambulance or loading bays; and parking garages that share structure with low-noise and low-vibration environments. These challenges are creating a paradigm shift in the vibration design of structures, whereby the structural scheme that satisfies ultimate limit states may no longer be sufficient to meet serviceability requirements.

In this paper we discuss the co-location of parking structures with vibration-sensitive spaces, and share some of the approaches to control that we have applied during the design of research labs and hospitals.   

  • First, we provide an overview of the nature of vehicle vibrations, which is important to understanding some of the approaches to source control.
  • This is followed by a discussion on serviceability criteria.
  • Finally, we provide some practical guidelines for control of vehicle vibrations in sensitive spaces.
