Structural Health Monitoring For Bridges
Health monitoring of large bridges shall be performed by simultaneous measurement of loads on the bridge and effects of these loads. It typically includes monitoring of:
- Wind and weather
- Traffic
- Prestressing and stay cables
- Deck
- Pylons
- Ground
Provided with this knowledge, the engineer can:
- Estimate the loads and their effects
- Estimate the state of fatigue
- Forecast the probable evolution of the bridge
The state of Oregon in the United States, Department of Transportation Bridge Engineering Department has developed and implemented a Structural Health Monitoring (SHM) program as referenced in this technical paper by Steven Lovejoy, Senior Engineer.
References are available that provide an introduction to the application of fiber optic sensors to Structural Health Monitoring on bridges.

Famous quotes containing the words structural, health and/or bridges:
“The reader uses his eyes as well as or instead of his ears and is in every way encouraged to take a more abstract view of the language he sees. The written or printed sentence lends itself to structural analysis as the spoken does not because the reader’s eye can play back and forth over the words, giving him time to divide the sentence into visually appreciated parts and to reflect on the grammatical function.”
—J. David Bolter (b. 1951)
“The filth and noise of the crowded streets soon destroy the elasticity of health which belongs to the country boy.”
—Rutherford Birchard Hayes (1822–1893)
“As night is withdrawn
From these sweet-springing meads and bursting boughs of May,
Dream, while the innumerable choir of day
Welcome the dawn.”
—Robert Bridges (1844–1930)
