Bridge Inspection Using Bridge Information Modeling (BrIM) and Unmanned Aerial Systems (UASs)

Creator:

Xu, Yiye

Abstract:

Bridge inspection is a critical task needed to monitor bridge quality and serviceability. In the U.S., 40% of bridges are more than 50 years old while most bridges are typically designed for a lifespan of 50 years. 9.1% of the 614,387 bridges across the U.S are considered structurally deficient. These...

Unmanned aircraft systems for bridge inspection : testing and developing end-to-end operational workflow

Creator:

Gillins, Matthew N.

Abstract:

Bridge inspections are vital for monitoring the health and serviceability of transportation infrastructure throughout the world. However, inspections can be logistically-challenging, expensive, and dangerous. For example, inspections may require climbing, as well as the use of scaffolding, ladders, rescue boats, bucket trucks, and/or under-bridge inspection vehicles. Small, multirotor unmanned aircraft...

Computer vision for geometrical analysis of bridge gusset plates

Creator:

Varakantham, Shravya

Abstract:

Gusset plates are an important component of bridges. They are thick sheets of steel that join steel members together using fasteners and also strengthen their joint. Transportation agencies regularly evaluate and rate their inventories of gusset plate connections using visual inspection, which is very costly. To address this issue, we...
