WebPart one of a three part webinar series, this session covers: • Horizontal forces acting on a house and how they are resisted• Code-prescribed limitat... WebA drag truss acting as diaphragm support and boundary chord requires boundary nailing stipulation. Drag trusses interior to a diaphragm will generally receive unit shears from two separate diaphragm spans. Both sequencing and pattern of the nailing must be evaluated. The staggered nature of the sheathing generally dictates the sequencing.
