Disclaimer: This tool provides estimates per IRC 2021 prescriptive provisions and NDS 2018 ASD for dimensional lumber studs. It checks pure axial compression (NDS §3.7) and, when a wind pressure is entered, combined out-of-plane bending + axial compression (NDS §3.9, Eq. 3.9-3) as a separate load case at CD = 1.6. Bending capacity assumes the compression edge is continuously supported by sheathing (CL = 1.0) and repetitive-member framing (Cr = 1.15); dry service, untreated, normal temperature (CM = Ct = Ci = 1.0). Shear, deflection, connections, and in-plane lateral forces must be verified separately. Oasis Engineering LLC assumes no liability for use of this tool. Verify all designs with a licensed structural engineer.
