Setting up stepStep-by-step moving-load analysis involves is initiated through the following stepsprocess:

• Define

  Vehicle (via "

  vehicle type through Define > Bridge Loads > Vehicles

  ")

  .

• Define

  Lane (via "

  the lane through Define > Bridge Loads > Lanes

  ")

  .

• Use "

  Select Define > Load Pattern

  " menu command

  (Figure 1) to define

  Load pattern of type BRIDGE LIVE. Click "

  the Type of load pattern Bridge Live. Select Modify Bridge Live

  Button"

  Load to define

  the parameters for this live load pattern, such

  such parameters as lanes, vehicles, vehicle speed, movement direction, etc.
