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. It also allows for the specification of a vertical seismic coefficient as well as a horizontal one.
The update includes a fix for handling geometries where multiple points have the same X-coordinate but different Y-coordinates. Note that AASHTO98/02 is based on allowable stress design (ASD) whereas AASHTO 2007-2010 is based on load resistance factor design (LRFD). It follows the design guidelines of AASHTO98/Demo 82, AASHTO02/FHWA-NHI-00-043, AASHTO 2007-2010, or NCMA97/98. 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. MSEW is an interactive program for the design and analysis of mechanically stabilized earth walls. And there is now an option for considering live load (LL) in calculating Tmax for strength and connection but ignoring it for pullout. 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). Update 9 to MSEW 3.0 was posted on April 25. ADAMA Software has released several updates to their popular MSE Wall design software and Reinforced Soil Slope software packages.
