Work Streams and relation with Work Packages

The ERA Technical Note defines 11 Work Streams (WS) that needed to be addressed for closing TSI open points on bridge dynamics. These WS will be thoroughly studied in InBridge4EU and will be addressed in 5 Technical-Scientific Work Packages (WP1 to WP6) and in one WP dedicated to normative recommendations (WP6). The relation between WS and WP defined in InBridge4EU is presented bellow.

How InBridge4EU connects with the ERA Technical Note
