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.
