ReSSA Major Update and MSEW Update
ADAMA Software has released update 9.2 for their Mechanically Stabilized Earth retaining wall design software, MSEW 3.0 as of December 12, 2008. They also released update 3.1 for ReSSA 3.0, a reinforced soil slope design program on January 15, 2009. The ReSSA update seems like a relatively minor one, but the MSEW update contains a number of updates related to AASHTO LRFD resistance factors and design methods.

Side-hill retaining walls refer primarily to fill-walls built partway down the sides of an existing slope or embankment. They are encountered in roadway and rail widening projects as well as site development but usually in steep terrain. This article provides an overview of the problems, failure mechanisms, investigation approaches, analysis tools and wall type alternatives for these structures. Click through to read the article!
