A Survey of Bridge-Maintenance Strategies

Abstract

We will present an overview of two of the principal management models used for maintaining and repairing bridges in the United States. "Failure" of a bridge is usually associated with the collapse of the bridge or even the failure of a single critical component of the bridge that can close the bridge down. Failures usually have disastrous consequences including a tragic loss of human lives or severe human injuries. Bridges are vital links in roadway networks because their failure can cause public and private losses. Therefore, it is essential to establish an effective maintenance-andrepair strategy to keep bridges sufficiently safe and serviceable throughout their service lives. It has been reported that many bridge failures can be prevented with timely preventive maintenance. We will present an overview of the statistical models used for studying bridge deterioration and failure. Further, we will discuss decision-making with respect to how often bridges should be maintained, and when they should be demolished.
