Types of Fasteners and Connections
Connection Stiffness
- mechanical
- adhesive
- glulam
- plywood
- OSB
- wood I-joists
- mechanical + adhesive
mechanical stiffness >> adhesive stiffness
Lateral / Shear Loading
- load ⊥ length
- number of shear planes
Use the weakest plane.
Parallel Loading
- load // length
- tension → withdrawal
- bearing stress under washer → compression ⊥ to grain
furniture cams (see C04)
Reference Design Values
Z - shear loading
W - withdrawal loadingidealized conditions
- 10-year duration
- dry conditions
- normal temperatures
