Calculation: 

Designer/Checker: 



Input: 




(Note: All input Metric units are converted to English units
for the equations below and then the output English units are converted back to
Metric) 





Yield strength of the steel reinforcement, (fy  ksi or kPa) 

(Use 40 ksi for Grade 40 or 48 ksi for Grade 60) 

Concrete compressive strength, (f'c psi or kPa) 

Distance to the horizontal resultant (Dh  ft or m) 

Horizontal soil resultant on the wall (Rh  kip/ft or N/m) 

Width of base of stem (h  in or cm) 

Distance from outside face of concrete to center of steel (Cvr  in or cm) 

Distance to the soil surcharge resultant (Dss  ft or m) 

Horizontal resultant from soil surcharge (Rss  kip/ft or N/m) 

Height of the Stem (Hs  ft or m)

Ratio of stress block depth to effective depth, ku = 

Area of steel required, As = 

Shear capacity, 0.85Vc = 

Shear force at distance d on stem, Vu = 



Minimum reinforcement ratio, pmin = 

Maximum reinforcement ratio, pmax = 

Reinforcement ratio, p = 

If pmin < p < pmax then ductility adequate. 

Temperature shrinkage reinforcement, Astemp = 0.0018bh =
