![]() ![]() While research is underway for vibrations in concrete and wood-framed floors, these design guidelines currently only exist for steel structures. ![]() This design guide greatly benefits engineers designing offices, laboratories, and steel stairs. The American Institute of Steel Construction (AISC) Steel Design Guide 11 was originally published in 1997 and updated in 2016 to assist engineers in determining how a steel-framed concrete floor over a metal deck will vibrate under walking excitation (e.g., a person walking down a hallway) or rhythmic (e.g., a workout class jumping up and down to music), and how the vibration will then progress around the building. While there is no code requirement for floor vibration design, there are guidelines that engineers utilize to help determine the anticipated vibration a floor will produce. ![]() Whether you have an existing building with future tenants in mind, new construction that should meet the needs of future tenants, or an existing tenant raising concerns, there are a few factors for owners to consider in meeting the floor vibration needs. In addition, building tenants frequently add floor vibration requirements to their leases to accommodate vibration-sensitive equipment. By Andrew Runnoe, PE, SE – Structural Engineer | Orange County Officeįloor vibration is a structural design consideration gaining attention in the southern California area, particularly with the increased presence of biomedical research facilities in the region. ![]()
