SDPWS Footnote 3: Species-Specific Gravity Adjustment per NDS Table 12.3.3A

Summary: Apply SDPWS Table 4.3A Footnote 3 when framing is not Douglas-Fir-Larch or Southern Pine. Free shear wall design calculator: Vn reduced using G from NDS…

Overview

Building / scenario

• Occupancy / use: Residential

Problem statement

An 8×8 ft shear wall has 7/16 in. OSB and 8d common nails at 6 in. spacing. Framing is Spruce-Pine-Fir (G = 0.42), not Douglas-Fir-Larch or Southern Pine. Wind load = 1,800 lb. SDPWS Footnote 3 requires Vn × [1-(0.5-G)]. Check capacity with this adjustment.

Workflow in StructSuite

StructSuite applies SDPWS Table 4.3A Footnote 3: Va = Vn × [1-(0.5-G)] when enabled. Species and G come from NDS Table 12.3.3A. Uses §4.1.4.2 for wind.
