Structural modeling and monitoring of the Rollins Road Bridge for condition assessment

The health of the US infrastructure is on the minds of everyone following the August 1, 2007 collapse of the I-35W Bridge in Minneapolis, Minnesota. The safety of bridges nationwide should be a top priority for both our citizens and government since they are the backbone of this nation\u27s economy, with 73% of all traffic and 90% of all truck traffic traveling over state-owned bridges. Performing nondestructive load tests, collecting structural response data, and structural modeling techniques allow bridge owners an objective insight into the health of a bridge. The art of reconciling the structural model to reflect collected field data also allows bridge owners to have an up-to-date analytical model of the bridge for condition assessment, decision-making, and asset management. The results from the Rollins Road Bridge load test accurately show that a model can be updated to match measured structural response from a nondestructive load test
