Load Distribution and Fatigue Cost Estimates of Heavy Truck Loads on Louisiana State Bridges, Tech Summary.

摘要

The objective of this research was to develop an integrated system for monitoring live load and verify the carrying capacity of highway bridges in Louisiana where heavy truck loads may have caused significant damage to state bridges. This study developed a monitoring system for synchronous measurement of live load and structural response of bridge components. The monitoring system integrated a distributed network of advanced strain and displacement sensors (continuous and peak). The anticipated major contributions include accumulated fatigue load spectra, strain measurements to determine in-service conditions, and adverse loading conditions on the bridge superstructure assessments.
