Since that time a lot of investigations and additional special measurements were devoted to innovative, mainly monitoring-based fatigue assessment as the emphasis is to replace the standard’s premises – referring to loading - by measurements. A long-term preoccupation of VCE with BRIMOSâ (BRIdge MOnitoring System) on the Europabrücke (since 1997) with regard to fatigue problems and possible damage led to the installation of a permanent monitoring system in 2003. It represents a bridge generation, where bridge designers acted on a maxim of building material economisation. The Europabrücke – a well known Austrian steel bridge near Innsbruck, opened in 1963 - is one of the main alpine north-south routes for urban and freight traffic. Bridges are ageing and traffic is growing, which creates a demand for accurate fatigue life assessment.
