Horizontal Subgrade Reaction Coefficient given Characteristic Pile Length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Coefficient of Horizontal Subgrade = Stiffness Of Pile/(Characteristic Pile Length)^2
n_h = EI/(T)^2
This formula uses 3 Variables

Variables Used

Coefficient of Horizontal Subgrade - Coefficient of horizontal subgrade is the reaction pressure sustained by the soil sample under standard conditions.

Lateral Deflection of Pile with Head Free to Move

Go Lateral Deflection = ((Coefficient Ay*Laterally Applied Load*(Characteristic Pile Length^3))/Stiffness Of Pile)+((Coefficient By*Moment in Soil*(Characteristic Pile Length^2))/Stiffness Of Pile)

Negative Moment Imposed on Pile

Go Moment Negative = ((Coefficient Aϑ*Lateral Load*Characteristic Pile Length)/Coefficient Bϑ)-((Angle of Rotation*Stiffness Of Pile)/(Coefficient Bϑ*Characteristic Pile Length))

Lateral Deflection for Fixed Head Pile Case

Go Lateral Deflection Fixed Head = ((Laterally Applied Load*(Characteristic Pile Length)^3)/Stiffness Of Pile)*(Coefficient Ay-((Coefficient Aϑ*Coefficient By)/Coefficient Bϑ))

Positive Moment Imposed on Pile

Go Moment Positive = (Coefficient of Lateral Load in Positive Moment*Laterally Applied Load*Characteristic Pile Length)+(Coefficient of Moment term in Positive Moment*Moment in Soil)

Pile Stiffness given Characteristic Pile Length for Laterally Loaded Piles

Go Stiffness Of Pile = ((Characteristic Pile Length)^2)*Coefficient of Horizontal Subgrade
