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

Earthquake K_ae and K_pe

Lateral earth pressure coefficients for earthquake conditions are calculated and presented based on horizontal and vertical ground accelerations (a_v,a_g). Therefore in LateralK program for ease of use, Kae and Kpe are calculated for every 0.05g step of a_v and a_g as tables. Please see screenshots for more clarifications. This way, User can find Kae and Kpe for all practical combination of a_v and a_g. Online documentation describes more details.

Reporting

All tables can be exported as text file. A report is also prepared summarizing all input data and assumptions along with output parameters (lateral earth pressure coefficients).
