What is the maximum span for wood structural panels rated 32/16 when used as floor sheathing for floors without wood strip flooring?

  1. 12 inches

  2. 16 inches

  3. 18 inches

  4. 24 inches

The correct answer is: 16 inches

The maximum span for wood structural panels rated 32/16 when used as floor sheathing for floors without wood strip flooring is 16 inches. This rating indicates the panel's ability to support load and the maximum spacing permitted for supports beneath the panels. In this context, the first number (32) refers to the maximum indicated supporting spacing for a roof under live loads, while the second number (16) refers to the maximum spacing of supports for floors under live loads. Ensuring that the appropriate panel span is adhered to is crucial, as it directly impacts the structural integrity and performance of the flooring system. Spacing the panels too far apart could lead to insufficient support, resulting in deflection and potential failure under load. Therefore, following the 16-inch maximum span guideline is essential for maintaining the structural safety and durability of the flooring system.
