To analyze load transfer from one member to another, BC Calc® software allows for a "Linked" Support Type. Linking two members, for example, joist supported by a beam, transfers the reaction and maintains a dynamic link. A change of load on the "supported" member will affect the load transferred or linked to the "supporting" member. The applied load can be a Uniform Linear Load or a Point Load, the reference end (left or right) can be set and the reaction can be configured as a side load if required.
For this exercise add two beams to an analysis, with the goal of side-loading one beam to the other:
1. Double-click on one of the members to edit.
2. From the Spans tab adjust one of the Support Types (bearings) to be Linked.
3. Once one of the bearings has been set to Linked, the Support Label will become a clickable link and will open the Linked Support properties. Click the word Link.
4. Linked Support:
(1) Select the member that we'll be applying a load to.
(2) Click the Load tab.
5. Linked Support Details:
(1) Select a Load Type.
(2) Enter the location of the load.
(3) Enable Side Load (Location Back or Front) and click Save
6. Configure the Products tab to specification or find an adequate solution.
NOTE: The connection may require review depending on the load applied.
7. To configure a product for the other member and review the load being applied, switch to the other beam from the Member drop-down menu.
8. After selecting a product, click Analyze Member .
9. Under the Loads tab, notice there's a reaction from the other member.
