For columns, wall studs and CLT wall panels loaded in axial compression, Sizer compares the compares the factored compressive strength parallel to the grain Fc' with the axial stress on the member fc. For members loaded in tension, it compares compares the factored tensile strength parallel to the grain Ft' with the axial tension stress on the member ft. If one load combination, such as a snow or live load combination, is in compression, and another combination, such as a wind combination, is in tension, the program designs for both conditions simultaneously. However, if there are two separate wind load cases providing uplift and downward loading, you must make separate runs and compare manually.
For solid columns and wall studs, refer to NDS 3.6 , 3.7 and C3.7.1 - Compression Members and Solid Columns for more details about axial compression design, and NDS 3.8 Tension Members for axial tension design. For built-up columns, refer to NDS 15.2 Built-up Columns. For CLT wall panels, refer to CLT Handbook 8, 4.1.4.1 - Axial Design for Wall Panels, Axial CLT Fire Design, and NDS C3.7.1 - Alternative Stability Factor for CLT Wall Panels.
