Structural Wood Design: Asd/lrfd -
"Factored" loads increase the design burden based on the uncertainty of the load type (e.g., higher factors for live loads vs. dead loads).
Applies a single Factor of Safety to the material's ultimate strength to determine "allowable" stresses. Loads: Uses actual expected (unfactored) service loads. Structural wood design: ASD/LRFD
The choice often depends on the specific project requirements or the engineer's preference: LRFD versus ASD for Wood Design "Factored" loads increase the design burden based on
