From Aprtl 7th to 9th, TESolution Vibration Control team visited Okuma bridge which is located in Nishitama-ken Tokyo-do, Japan.
Okuma bridge TMD is quite different from TMD on most of the bridges as it not only controls the vertical vibration from wind load, but also incorporates Torsion Spring to minimize the friction. TMDs installed on Okuma bridge consist of 8 TMDS and each has 1 ton of moving mass.
Prof. Fujino of University of Tokyo, led our group and explained about the devices through out the tour.
