Segmental Retaining Wall Analysis & Design

Module Summary

  • Our Segmental Retaining Wall module was completely revised in 2019 to support calculations from NCMA Design Manual for Segmental Retaining Walls – 3rd Edition.
  • Most NCMA 3rd edition failure modes are supported.
  • Calculations offer both seismic and non-seismic conditions.
  • Additional factors of safety are supported – including designer control over minimum acceptable factors (or use standard values).
  • More internal values are provided for back-checking and review.

Manufacturer Block Data Included

Our Segmental Retaining Wall module includes manufacturer block data for Allan Block, Anchor Retaining Wall, Keystone Retaining Wall, and Versa-Lok. You may also enter your own block data and reference it repeatedly without having to re-enter it.

Manufacturer Geogrid Data Included

Our Segmental Retaining Wall module includes geogrid data for Mirafi, Strata Systems, and Versa-Grid. You can enter your own geogrid data and reference it repeatedly without having to re-enter it.

Failure Modes

Our segmental wall module tests for the following failure modes:

  • Base Sliding
  • Overturning
  • Bearing
  • Internal Sliding
  • Tensile Overstress
  • Pullout
  • Connection

History

ENERCALC’s earth-retention modules originated in RetainPro, which was originally designed by the ENERCALC founder’s father (Hugh Brooks, PE), a California structural engineer. In 2020, all of RetainPro’s modules were overhauled and incorporated into ENERCALC where they are now maintained.
