Vibration heat maps
We’ve correlated our field measurements to our engineering models continuously over a decade and refined our modeling strategies to predict real vibration response more accurately. Moreover, we developed algorithms that work closely with our models to generate footfall vibration heat maps for floors with sensitive occupancies.
Vibration heat maps make optimized programming easy with vibration sensitive occupancies. They also provide a visual guide for cost-effective, focused vibration design of the structural floor framing.
Brigham and Women's Faulkner Hospital
The project included a five-story inpatient addition to Brigham and Women’s Faulkner hospital. Floor vibration requirements of inpatient rooms are more stringent than offices. Enhanced vibration analyses were performed as part of the structural floor design.
Inpatient hospital floors were designed for a maximum floor vibration velocity following the recommendations of the Guidelines for Design and Construction of Hospitals and Outpatient Facilities.
A finite element model of the typical inpatient floor was built based on the most up-to-date structural and architectural drawings. Next, enhanced footfall vibration analyses were conducted with consideration for respective walking speeds inside the rooms and along the corridors. Resulting floor vibration levels were presented as heat maps and evaluated against the vibration criteria. Structural floor framing was selectively optimized utilizing the heat maps.
