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.
| Work Package | Work Streams addressed |

WP1 Definition of Dynamic Train Categories (DTCs) for ensuring compatibility of the interface between trains and bridges Leader: UPM |
WS1 - Further development of spectral methods (DER, LIR) WS2 - Definition of dynamic loading interface between vehicles and bridges) WS4 - Sensitivity studies on passenger and freight train parameters WS5 - Selection of relevant vehicles in train families WS11 - Revision of limits of validity of static vehicle / bridge compatibility checks (together with WP6) |
|
WP2 Identification of critical bridge parameters for the assessment of the economic impact of the new DTCs Leader: UJI |
WS3 - Economic evaluation of proposed Dynamic Train Categories (DTCs)
