MSEW+ is an interactive program for the design and analysis of mechanically stabilized earth walls.
It follows the design guidelines of:
AASHTO98 /Demo 82
AASHTO02/FHWA-NHI-00-043
AASHTO 2007-2010
FHWA-NHI-10-024 (as related to traffic barrier load and some of the bridge abutment methodology)
NCMA1997
AASHTO 2017-2020. Simplified AASHTO Method for geosynthetics and metallic reinforcement as well as an option for using Coherent Gravity Method for metallic.
AASHTO 2020 Simplified Stiffness Method for geosynthetics which can be used instead of the Simplified AASHTO.
Note: An alternative method for designing geosynthetic walls allowed in AASHTO 2020 is based on limit equilibrium (LE). Its unique feature is its ability to rationally deal with internal stability. This LE has been implemented in program ReSSA+. Hence, the two programs MSEW+ and ReSSA+ complement each other.
