Problem Statement: Joist Bearing Length Design*
The goal of this assignment is to determine the minimum bearing length required for single-span floor joists based on the given structural loading conditions and material properties.
Given Data:
- Joist Type & [Grade]: S-P-F sawn lumber [No.1/No.2]
- Joist Size: 2” × 8”
- Joist Span: 10’
- Joist Spacing: 16” (center-to-center)
- Specified Dead Load: 30 psf (includes partitions)
- Specified Live Load: 50 psf (commercial use and occupancy)
- Load Duration: Standard
- Service Condition: Dry
- Lateral Support: Fully supported by Douglas fir plywood (DFP) subfloor
- Bearing support: Beam, Timber-soft material, S-P-F No.2
Design Requirement:
Use the software to determine the minimum bearing length required at the supports, considering the compression perpendicular to grain capacity of S-P-F No.1/No.2 lumber to ensure structural adequacy under the applied loads.
Select the most appropriate answer based on the software output and standard design requirements.
