Link Settings for Beams |

When linking reactions to the active beam calculation, there are three main components to this portion of the window:
1) Linked Load Quantity: Start by specifying how many times the support reaction should occur at each location by updating the "Apply Linked Load ___ times at ea. location" input. This can be useful when a given support reaction occurs multiple times at a single location on the active beam (for example, when an infill beam frames into each side of a girder).
2) Linked Load Location: Next, specify where the support reaction occurs on the current beam. The available options are:
Specify: Specify an exact location for the load.
•Selecting "Beam" measures the dimension from the far left end of the beam regardless of support conditions. The resulting linked load will always be at this fixed dimension even if the underlying span lengths and quantities change. This dimensional value is restricted to the maximum length of the entire beam. If span length adjustments cause the load to extend beyond the beam's end, it will automatically reposition to the far right end of the beam.
•Selecting "Selected Span" measures the dimension from the left end of the currently selected span. The resulting linked load will always correspond to the span index of the selected span. For example, if there are two spans and the second span is selected, the linked load will apply to the second span (span index = 2). As long as there are at least two spans, the linked load will consistently be associated with span index 2, regardless of any spans that are added or deleted in the future.
Midspan, 1/3 Pts, & 1/4 Pts: Automatically place the load at the midspan, one-third points, or one-quarter points. These locations are relative to the span length and will adjust automatically if the span lengths change.
•Selecting "All Spans" will apply the linked load to all spans within the currently active beam calculation, including any new spans which may be created in the future.
•Selecting "Selected Span" will apply the linked load to the span index of the currently selected span. As described above, the resulting linked load will always correspond to the span index of the selected span regardless of any spans that are added or deleted in the future.
Spacing: Specify repetitive loads by defining a start point and a spacing. The first load will be placed at the "From" dimension, and additional loads will be repeated at the defined spacing throughout the entire length of the beam.
3) Add the Linked Load: Once you have defined the settings for the linked load, click the Link Load button.
Once you've click the Link Load button, you will see that the new linked load has been added to the Linked Reactions Table.
