In the reconstruction of the cafeteria building, measures were implemented directly beneath the structure! A case was confirmed where vibration reduction of 8 to 11 dB was achieved.
At Ishiguro Construction in Toyama Prefecture, road traffic vibrations from the surrounding roads of the steel manufacturing facility and operational vibrations from the truck scale within the facility were propagating to the cafeteria building on the same site, causing vibration issues. Therefore, during the reconstruction of the cafeteria building, the 'WIB method' was implemented directly beneath the building. Vibration measurements conducted before and after the countermeasures confirmed that vertical vibrations within the cafeteria building were reduced by 8 to 11 dB. [Case Summary] ■ Location: Toyama Prefecture ■ Client: Ishiguro Construction Co., Ltd. ■ Vibration Sources: Road traffic vibrations, operational vibrations within the facility ■ Protected Target: Cafeteria building within the steel manufacturing facility ■ Countermeasure Work: Plate-type WIB (honeycomb cell type) ■ Installation Position: Directly beneath the receiving side *For more details, please refer to the PDF document or feel free to contact us.
