What is the maximum allowable span for cold-formed steel joists size 800S162-43 with a live load of 40 PSF and spaced 16 inches OC?

• A. 13′-5″
• B. 12′-3″
• C. 15′-1″
• D. 17'-0"

Answer: (A)

The maximum allowable span for cold-formed steel joists, such as size 800S162-43, is determined by the materials characteristics, loading conditions, and spacing. For a live load of 40 PSF and a spacing of 16 inches on center, the specified span of 13 feet 5 inches is deemed appropriate based on engineering standards and design codes. In cold-formed steel design, calculations take into account the properties of the material, including its yield strength, geometry, and capacity to support loads without buckling or failing. The referenced span of 13 feet 5 inches fits within these parameters, ensuring structural integrity and safety under the applied load conditions. Moreover, selecting spans that are too long can lead to inadequate support and increased risk of structural failure, while spans that are too short may result in unnecessary material costs or weight. Therefore, choosing 13 feet 5 inches aligns with best practices in the construction industry where efficiency, safety, and compliance with building codes are critical. Ultimately, understanding these parameters helps builders and designers make informed decisions ensuring their constructions not only meet required safety standards but also are cost-effective and practical.
