JOISTS (Cont’d)
- By inspection, the 2x6 appears to be the lightest joist that would be satisfactory on a 48-in. span.
- But also consider the 4x4 which has an allowable span of 53 in. at 400 lb/lf. The 4x4 is often selected for this type of form, because its shape provides inherent lateral stability.
Bearing
- A check of bearing stresses where joists rest on stringers and where stringers rest on shores would be advisable.
