Full List of Design Assumptions for All Axial Load Tables
- Studs loaded through centroid.
- Fully effective lateral bracing at 4’ o.c. vertically.
- Uniform loads equally distributed to all studs.
- Allowable axial loads listed in kips (1 kip = 1000 pounds).
- Allowable axial loads determined in accordance with AISI S100-16/S1-18 in accordance with the 2021 IBC, assuming that all axial loads pass through the geometric center of the section
- Allowable axial loads based on lateral and torsional bracing at a maximum spacing of 48 inches on center.
- End supports have not been checked for web crippling.
- All tables are based on simple span.
- Studs that have h/t>200 are not available choices.
- Stud distortional buckling moment based on assumed Kφ = 0
- The 5 psf live load has not been reduced for deflection. For 10 psf and higher wind pressure: IBC 2021/ASCE 7-16: Because of changes in building codes, wind pressures determined using codes that reference ASCE 7-10 or ASCE 7-16 are strength level loads (LRFD) in comparison to those determined in earlier IBC codes which were service level loads (ASD). The load/span tables that follow are based on service level (ASD) wind loads. Therefore, to properly use the load/span tables in this catalog, multiply the IBC (2012 - 2021) design wind pressures by 0.6 (Reference section 2.4 ASCE 7-16) prior to entering the load/span tables.
Example:
* ASCE 7-16 Calculated Design Wind Pressure = 25 psf (Strength level loads, LRFD)
* Convert to service level loads (ASD) = 25 psf x 0.6 = 15 psf
* Use 15 psf as the Pressure Value used in this Table to determine the member capacity
For codes that use ASD wind speeds: These tables are based on service level (ASD) wind speeds. Therefore, the pressures calculated using the ASD wind speeds do not need to be modified prior to using the tables.
