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 ...

Kinetics of mixing-water repartition in UHPFRC paste and its effect on hydration and microstructural development

Eugen Brühwiler, Emmanuel Denarié, Karen Scrivener, Mohammadhadi Kazemi Kamyab, Arnaud Charles Albert Muller

The hydration of an ultra-high performance fibre reinforced concrete (UHPFRC) paste with a water to cement ratio of 0.18 was followed by proton nuclear magnetic resonance (1H NMR) alongside more classical techniques for hydration kinetics, and microstructu ...

Long term monitoring of a UHPFRC-strengthened bridge deck slab using strain gauges

Eugen Brühwiler, Bartlomiej Wojciech Sawicki

The Chillon viaducts, in service since 1969, are two parallel structures with a total length of 2.1km each and spans varying from 92 to 104 meters. This post-tensioned precast concrete structure was strengthened with UHPFRC (Ultra High Performance Fiber Re ...

Numerical simulation of the probability of corrosion initiation of RC elements made of reinforcing steel with improved corrosion performance

Eugen Brühwiler, David Conciatori

Steel reinforcing bars in concrete are protected from corrosion by a thin oxide film that is created on the steel surface in the highly alkaline environment of the concrete. Corrosion process begins once this oxide film is destroyed, for example, by chlori ...

“Pocket-Monitoring” for the fatigue safety verification of bridge members in steel and reinforced concrete

Eugen Brühwiler

The fatigue safety of the reinforced concrete deck slab of a sixty-year-old steel-concrete road viaduct as well as the riveted steel girders of a 130 year old railway bridge was questioned based on the results of conventional assessment consisting in "re-c ...
