17 Connections Tutorial 4 - Design Collectors or Drag Strut (Canadian) In this tutorial, it will be demonstrated how the results from a WoodWorks shearwalls model can be interpreted to complete connection design of a collector or drag strut. Good Engineering judgement should be used when designing collectors or drag struts within shearlines. The forces used in this model come from the shearwalls model which is created by going through Shearwalls tutorial 6. Click here to download the connections file (.des) created from going through this tutorial. 4.1 Drag Strut Force from Shearwalls model Connections Tutorial 4 - Designing Collector along Shearline B Level 1 Upon reviewing the forces in the elevation view, it can be observed that the worst case loading scenario is when seismic loads are distributed by a Flexible diaphragm. The two portions of shearline B (B-1 and B-2) need to be connected by a collector that can resist an 5030 lbs tension force. To resist the 5030 lbs tension force, it will be necessary to specify a steel strap that can drag the kn between the two shearline segments. Based on the model created in concept mode, it has been determined that the joists in the diaphragm above the shearwalls run parallel to the shearline. It will be necessary to create a continuous row of beams or blocking between segments B-1 and B-2 of the shearline. The steel strap will be nailed from the top plate of wall B-1 and be continuously nailed to blocking or beams on the underside of the diaphragm until it reached the top plate of Wall B-2. For more information on designing drag struts, please refer to Thor Matteson s Wood-Framed shear wall construction.
