Setting up step-by-step moving load analysis involves the following steps:

* Define [kb:Vehicle] (via "Define > Bridge Loads > Vehicles")
* Define [kb:Lane] (via "Define > Bridge Loads > Lanes")
* Use "Define > Load Pattern" menu command to define [kb:Load pattern] of type BRIDGE LIVE. Click "Modify Bridge Live Button" to define the parameters for this live load pattern, such as lanes, vehicles, vehicle speed, movement direction, etc.

* This will automatically create a Multi-step static load case that you can review using "Define > Load Cases" menu command.
* You can also evaluate dynamic response by changing the load case type from "Multi-step Static" to "Time History" and setting analysis type to nonlinear, direct-integration. Set the damping and other parameters as necessary.
