Abstract

The Long-Term Bridge Performance (LTBP) program was started by the Federal Highway Administration (FHWA) in 2009 to gather high-quality data on a collection of typical bridges over a twenty-year period of time. The goal of this program is to create databases of high quality data acquired through long-term instrumentation of the bridges behavior during their service life.

The data gathered will be used to improve design practices and effective management of infrastructures. As part of the LTBP Program two integral abutment bridges, a California Bridge near Sacramento, CA and a Utah Bridge near Perry, UT, were selected to be monitored for temperature changes as well as to undergo periodic live-load testing. Live-load testing included slowly driving a truck over the bridges.

The bridges were instrumented to collect test data and use it to calibrate a finite-element model. This finite-element model was used to determine the actual bridge behavior and compare it with the AASHTO LRFD Specifications.
