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)

Novo Tech Software addresses the challenges and issues that geotechnical engineers find themselves facing today.

Novo Tech creates software tools that help geotechnical engineering firms perform soil assessments. We look forward to hearing from you.
 

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_h. Online documentation describes more details.

Reporting & Exporting the Results

All tables can be exported as to MS Excel files. Graphs can also be saved as image files.
