Connector Testing

"For wood connectors, ICC-ES AC13 and ASTM D7147 require a safety factor of 3 on ultimate and have an 1/8" deflection limit for serviceability. In addition, the load rating includes a fastener calculation and wood bearing calculation in accordance with NDS standards."  (source)

• D7147 Standard Specification for Testing and Establishing Allowable Loads of Joist Hangers

"We then did dozens of iterations of physical testing plus scores of simulations using finite element analysis to refine the parts. We varied the rolled edges and embossments, tried different fasteners and adjusted fastener locations until we achieved the best load at the lowest installed cost. After all of that, we tested the final products one more time for the code report."  (source)

Considerations

1. capacity required
2. size and type of members being connected
3. species of wood being connected
4. slope and skew of member
5. connector type preference
6. type of fasteners to be used
7. corrosion resistance desired
8. appearance desired
