A simple light-framed wood building is subjected to the load conditions as specified.
Along rafter length:
- Roof pitch: 9:12
- Dead load (roofing + sheathing + ceiling + rafters) = 30 psf
- Live load (snow) = 50 psf
- Ridge beam spans 16 feet from column support to column support
Please round to the nearest one-tenth (i.e., 0.1).
Determine the equivalent (horizontally projected) total load on the rafters = Answer 1 Question 1 lb/ft
Determine the load per foot on the bearing wall (at the bottom), including the wall weight (wall dead load = 10 psf and wall height, H = 8 ft) = Answer 2 Question 1 lb/ft
Determine the load per foot on the ridge beam = Answer 3 Question 1 lb/ft
Determine the load on the Interior column = Answer 4 Question 1 lb
Floor load conditions:
- Floor dead load (flooring + subfloor + joists) = 25 psf
- Live load (occupancy) = 150 psf
Determine the floor joist reactions into load per foot on the continuous foundation (one side) = Answer 5 Question 1 lb/ft
Determine the floor joist reactions into load per foot on the floor beam = Answer 6 Question 1 lb/ft
Foundation conditions:
- Continuous foundation's stem wall is 8 inch thick and 2 ft tall
- Footing base is 8 inch thick
- Concrete density = 150 pcf
- Soil bearing capacity = 1000 psf
Determine the minimum theoretical width of the continuous foundation = Answer 7 Question 1 ft (Round to the nearest tenth!)
Determine the minimum theoretical width of the interior spread footing for the critical center column = Answer 8 Question 1 ft (Round to the nearest tenth!)
