Mononobe-Okabe (MSEW vs. Gravity Walls)
Mononobe-Okabe (MSEW vs. Gravity Walls)
(OP)
I am in the process of developing geotechnical recommendations for performing seismic analyses on Mechanically Stabilized Earth (MSE) Walls and also for Concrete Gravity Walls. According to DOT specs, the Mononobe-Okabe Method is required.
I am familiar with the seismic analysis on Concrete Gravity walls, but not with MSE walls. Is there a special approach when dealing with MSE walls? If so, can someone provide me some references?
Thank You

RE: Mononobe-Okabe (MSEW vs. Gravity Walls)
The publication is FHWA A-NHI-00-043
http://www.fhwa.dot.gov/bridge/geopub.HTM
Select "Reinforced Soils Structures"
Select Document no. NHI-00-43
It is a pdf file and the title is "Mechnically Stabilized Earth Walls and Reinforced Soil Slopes Design and Construction Guidelines"
and look at page 98 - seismic design
It has all kinds of information about MSEW. i think they also has a software on MSEW where you can download it too.
Hope that this helps you along
