Ambient Vibration Monitoring on a Bridge
Project Overview
Tiered Wireless Sensor Network for Structural Vibration Monitoring on a Large Suspension Bridge.
Vincent Thomas Bridge: 6,000ft long suspension bridge with a main suspension span of 1,500ft, and a height of 185ft above water. We instrumented 600ft of the bridge using tiered wireless netwokr consisting of five master nodes and 20 motes, and collected data for 24 hours.

Software
The bridge experiment was done using Tenet software with
one additional hardware-dependent element 'SampleMDA400'.
This element was required to sample data through MDA400 vibration board.
You can download the Tenet software from the
ENL CVS

Directions to VTB
Map
If you are coming from the east, exit off of route 47 just prior to getting on the VTB which is the Ferry exit.
If you are coming from the west, cross over the bridge and take the first exit after crossing the bridge, which is also the Ferry exit.
Take Ferry St to Terminal Way and turn right.
Drive just past Earle St and turn right into a private drive.
This private drive is only about 50 feet or so past Earle St.
Take this drive all the way to almost the bridge pillars and you will see a building which is referred to as the paint shop.
Note the private road just past Earle Street.
Also, it may look like there is shorter way, but many of the streets are closed due to security.
