Reliability assessment of existing reinforced concrete bridges and viaducts through proof load testing

In the assessment of existing infrastructure performing only a desk study is often not sufficient to determine the structural reliability of a bridge or viaduct. For concrete structures gathering field data by performing a proof load test offers detailed information about the structural performance. However, the relation between the magnitude...

Towards structural modelling of alkali-silica reaction in concrete

Structures affected by Alkali-Silica Reaction (ASR) include large massive concrete dams and bridges, which are considered essential for the infrastructure system, and not easily replaceable. The main feature of this reaction is the creation of a hydrophobic expansive gel which causes internal damage in the concrete. This damage is strongly...
