Below are many different numeric parameters of wood and wood bearing walls. Many are estimations and vary widely based on the type of wood being examined.

 

Typical Wood Elastic Modulus: 640,000 to 2,280,000 psi

 

Typical Wood Allowable Bending Stress: 2,800-3,000 psi

 

Wood Modulus of Rupture: 12,500 psi

 

Typical Span: ~30 ft

Maximum Span: ~100 ft

(Please look for more information about span in Table 3)

 

Typical Height: 10-12 ft

(Please look for more information about height in Table 1. There is information listed about one storey, two storey, and three storey buildings.)

 

Typical System Thickness: ~8 in (total wall)

Minimum System Thickness: 6 in (total wall)

 

Please refer to Table 2 to learn more about the spacing of the studs in bearing walls. It includes information about one storey, two storey, andthree storey buildings.

 

Typical Bay Area: ~90 ft^2

 

Typical Bay Self-Weight: 1.1 psf

 

Time Typical to Erect One Bay: 1 to 2 days

 

Average Height of Buildings Using Bearing Walls: 5 stories and below

(Buildings can be made taller than 5 stories, but 5 and below are the most common)
