Vibration Design of Pedestrian Bridges

Synchronized movements of pedestrians can render an otherwise successful bridge design an annoyance for the users and the stakeholders. We build detailed finite element models of bridges, perform enhanced vibration analyses that consider both vertical and lateral directions and design structural members to meet the vibration performance goals without overdesigning any of the structural elements.

Boston, MA

Fazzalari Sky Bridge at BCH

Project Highlights 

The Fazzalari Sky Bridge is a three-span, steel truss pedestrian bridge with glass enclosure. The largest span length reaches to 100 feet. Both vertical and horizontal vibrations due to pedestrian walking were considered in the design of the structural system.

Vibration Criteria 

Maximum peak acceleration was selected as indoor footbridge vibration criteria following the recommendations of the American Institute for Steel Construction.

Boston, MA

Omni Boston Hotel at the Seaport

Project Highlights 

The pedestrian bridge is a single span, steel truss bridge with a span length over 125 ft. Both vertical and horizontal vibrations due to pedestrian walking were considered in the design of the structural system.

Vibration Criteria

Maximum peak acceleration was selected as indoor footbridge vibration criteria following the recommendations of the American Institute for Steel Construction.
