Innovation: |
13 Military Tank Proof Load Testing Determines Capacity of Bridges |
|

|
Year: |
2000 |

|
Description: |
This method uses M-60 or M-1 tanks as proof load to verify the load carrying capacity of bridges. Analytical evaluations tend to underestimate a bridge’s carrying capacity, and proof loading may save a bridge that is deemed unsound by analytical methods, thus saving the replacement cost of the bridge. Each tank weighs about 60 tons and has a track length of about 5 meters. Sensors are placed on the bridge structure and readings are taken as the tank moves across the bridge. Military tanks have an advantage over proof loading bridges with concrete blocks, because a tank is self-propelled, and a crane is not required to move the load. |
