After selecting a support reaction, you must define how the support reaction will be applied to the active calculation. The Link Settings will differ slightly based on the type of active calculation.
Link Settings for Beam Modules:
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.
Link Settings for Column Modules:
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 column (for example, when multiple beams frame into each side of a column).
2) Load Eccentricity: Specify the "X" and "Y" eccentricities to generate moments about the Y-Y and X-X axes, respectively. You can also choose whether the eccentricity is measured from the column centroid or from the column edge, similar to how typical applied loads are handled.
3) Linked Load Location: Define the vertical position of the axial load relative to the bottom of the column. Options include:
Specify: Manually enter an exact location from the bottom of the column.
Top of Column: The load is applied at the top of column. This location will automatically adjust if the column height changes.
4) 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.
