LateralK 

LateralK is a simple software for calculating lateral earth pressure coefficients behind retaining walls in static and earthquake condition. The following features are incorporated into LateralK program:

Rankine formulae for static condition, including Active earth pressure and Passive earth pressure coefficient (Ka, Kp)

Coulomb formula for static condition, including Active earth pressure and Passive earth pressure coefficient (Ka, Kp)

Jacky formula for At-rest earth pressure coefficient (Ko)

Mononobe-Okabe formula for earthquake condition, including Active earth pressure and Passive earth pressure coefficient (Kae, KPe)
