Quantification of the conditional value of SHM data for the fatigue safety evaluation of a road viaduct

Eugen Brühwiler, Imane Bayane

Fatigue safety verification of existing bridges that uses ‘‘re-calculation’’ based on codes, usually results in insufficient fatigue safety, triggering invasive interventions. Instead of “re-calculation”, Structural Health Monitoring (SHM) should be used f ...

Measurement-system design framework using multi-objective optimization for bridge load testing”

Ian Smith, Numa Joy Bertola

Due to conservative design models and safe construction practices, civil-infrastructure elements, such as bridges, usually have unknown amounts of reserve capacity that exceed code requirements. The quantification of this reserve capacity may lead to bette ...

Probabilistic reliability framework for assessment of concrete fatigue of existing RC bridge deck slabs using data from monitoring

Eugen Brühwiler, Imane Bayane, Amol Mankar

Assessment of existing bridge structures for inherent safety level or for lifetime extension purposes is often more challenging than designing new ones. With increasing magnitude and frequency of axle loads, reinforced concrete bridge decks are susceptible ...

Strengthening of a 19th-century roadway metallic bridge using nonprestressed bonded and prestressed unbonded CFRP plates

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

This paper summarizes the strengthening of a historically significant 122-year-old roadway metallic bridge using nonprestressed bonded carbon fiber reinforced polymer (CFRP) plates. Prior to the bridge strengthening, sets of laboratory tests were conducted ...
