As it can be seen in the following screenshot, there are three sets of input parameters in LateralK program:


 

Soil Properties

Φ : Internal friction angle of soil in degrees (between 0 and 55)

δ : Angle of friction between soil and concrete as ratio of F

γ : Unit weight of backfill material

 

Geometry

α : Back-slope angle in degrees

β : Batter angle of rear face of the retaining wall

Total Height of the wall, and buried portion of the wall

 

Seismic Parameters

Horizontal and vertical peak ground accelerations

 

When all parameters are entered, press the Calculate button to view the results.
