Line Load Assignments Form

Additional form: Bridge Line Load Definition Data

Use the Bridge > Bridge Objects > Loads > Line Loads command to assign line loads to the selected bridge object.

  1. Select the Bridge Object to which line loads are being assigned using the Bridge Object drop-down list at the beginning of the Bridge >  Bridge Object panel.

  2. Click Bridge > Bridge Objects > Loads > Line Loads command to access the Line Load Assignments form.

  3. Click the Add New button to fill the Load Data area with previously defined Load Patterns and Line Loads.

  4. Click in the Load Pattern drop-down list and choose the load pattern to which this line load assignment is being made.

  5. Click the Area Load Name drop-down list to select the previously defined line load to be assigned  to the Bridge Object.

  6. Use the Start Station and End Station edit boxes to place the line load by specifying the distance from the start of the bridge, as viewed from left to right. Note that the location of the line load relative to the edge of the bridge object (or deck) is specified on the Bridge Line Load Definition Data form. As necessary use the Transverse Variation drop-down lists to display a list of previously defined parametric variations for the load alignment on the Bridge Object.

  7. Use the Up and Down buttons to move the highlighted load data up or down in the list. The sequence in which the loads appear in the list has no effect on how the loads are applied during analysis and design/rating.

The Add Copy and Delete buttons can be used to copy the highlighted row of  load data in the Load Data area, or to delete the highlighted row of load data in the Load Data area of the form.
