ReSSA Major Update and MSEW Update
Software Updates
ADAMA Software Updates – MSEW and ReSSA
ADAMA Software has released several updates to their popular MSE Wall design software and Reinforced Soil Slope software packages. Update 9 to MSEW 3.0 was posted on April 25. The changes include several updates related to the AASHTO 2007 code, and the option to use either the Simplified Method (AASHTO) or the Coherent Gravity Method (CGM). And there is now an option for considering live load (LL) in calculating Tmax for strength and connection but ignoring it for pullout.
Update 2.2 to ReSSA 3.0 was posted yesterday, May 5 after several itterations of the update were posted during the month of April. The update includes a fix for handling geometries where multiple points have the same X-coordinate but different Y-coordinates. It also allows for the specification of a vertical seismic coefficient as well as a horizontal one. And the latest updates allow the inclusion of the safety map in the printout, include modified calculations of reinforcement quantities, and allow user-selected colors for reinforcement layers that now shows up in the printout too.

Side Hill Retaining Walls – Part 2
In this part 2 of 2, various types of retaining walls are examined as possible alternatives in a side-hill retaining wall situation. These include conventional wall types such as CIP walls, MSE walls, gravity walls and soldier pile walls and some less conventional approaches such as lighweight concrete fill, hybrid soil-nail and geofoam wall systems, ground improvement and micropile walls.
Part 1 of this Side Hill Retaining Wall article covered the definition, significance, problems and failure modes, investigation techniques, analysis, and construction considerations of side hill walls.
