[WIB Construction Method Case Study] Road Traffic Vibration Mitigation for Residential Areas Along Elevated Bridges

Reduced vibrations of 4Hz by about 5dB and vibrations of 12.5 to 20Hz by about 10dB! The vibrations have become such that they do not affect livability!

The planned construction site for housing in Kanagawa Prefecture was experiencing traffic vibrations transmitted from the elevated bridge and the road in front of the site. As a countermeasure, we implemented measures directly beneath the apartment building. The vibrations from the elevated bridge were predominantly at 4Hz, while those from the road in front of the site ranged from 12.5 to 20Hz. We designed the "WIB method" to address each of these vibrations. As a result, we reduced the 4Hz vibrations by approximately 5dB and the 12.5 to 20Hz vibrations by about 10dB, resulting in vibrations that did not affect livability. [Case Summary] ■ Construction Location: Kanagawa Prefecture ■ Client: Housing Manufacturer ■ Vibration Source: Road Traffic Vibration ■ Preservation Target: Apartment Building (New Construction, 3 Stories) ■ Countermeasure: Plate-type WIB Method (Honeycomb Cell Type) ■ Construction Position: Directly Beneath the Receiving Side *For more details, please refer to the PDF document or feel free to contact us.
