Additional form: Bridge Point Load Definition Data
Use the Bridge > Bridge Objects > Loads > Point Loads command to assign point loads to the selected bridge object.
Select the Bridge Object to which point loads are being assigned using the Bridge Object drop-down list at the beginning of the Bridge > Bridge Object panel.
Click Bridge > Bridge Objects > Loads > Point Loads command to access the Point Load Assignments form.
Alternatively, click the Home > Bridge Wizard command; select the Bridge Object to which the point load is being applied; highlight the Point Loads item in the Bridge Object Assignments area; click the Assign/Show Point Loads button to access the Point Load Assignments form.
Click the Add New button to fill the Load Data area with previously defined Load Patterns and Line Loads.
If no Load Patterns have been defined for the model, click the Define Load Patterns button to display the Define Load Patterns form; use that form to define a new load pattern or modify or delete an existing load.
If no Point Loads have been defined for the model, click the Define Point Loads button to display the Bridge Point Load Definitions form with an Add New Point Load button and an Add Copy of Point Load button that access the Bridge Point Load Definition Data form, which can be used to add a new point load. The Bridge Point Load Definitions form also has a Modify/Show Point Load button and a Delete Point Load button for modifying or deleting an existing load.
Click in the Load Pattern drop-down list and choose the load pattern to which this point load assignment is being made.
Click the Area Load Name drop-down list to select the previously defined point load to be assigned to the Bridge Object.
Use the Start Station edit box 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 point load relative to the edge of the bridge object (or deck) is specified on the Bridge Point Load Definition Data form.
Use the Spacing edit box to specify the distance between the number of point loads specified in the Number edit box.
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.
If no Parametric Variations have been defined, click the Define Variations button to display the Define Parametric Variations form and add, modify or delete a variation definition that can be used to specify a change in the alignment of the line load.
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.
