Moving Load Cases Eurocode-Optimization – MIDAS Support

1. Description

This component operates the Moving Load Cases Eurocode function in Civil NX.
Use the entered vehicle load classes and the traffic lanes to create moving load cases. Define type of vehicle, number of lanes, and the method to be used in moving load analysis.

The Moving Load Cases Eurocode function can be found in the Civil NX main menu,select
[Load] tab > [Moving Load(Type)] group > [Moving Load Code] Menu > [Moving Load Cases] Menu
