Mononobe-Okabe (MSEW vs. Gravity Walls)

[Davidmat]

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

I don't know if this can help you. There is a comprehensive publication by FHWA, where you can download it (418 pages).
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
