Project Notes

Sample House Component Check

2. Check a floor/ceiling joist (between the first and second stories) for bending. (see beam homework from chapter 6)

Loads w_D = 15 lb/ft
w_L = 53 lb/ft

Load combination needs to be determined

Span L = 14 ft

Trial member size 2x10

Stress grade and species No. 1 Spruce-Pine-Fir

Spacing 16 in. OC

Unbraced length l_u = 0

Moisture content MC ≤ 19%

Deflection limits 0.47 in. for L
0.70 in. for (D + L), or (L + 0.5D) if under dry conditions

Dry-service conditions

Normal temperatures

Bending about strong axis
