Version 3.0 takes everything from previous software versions and adapts it to the latest standards
National Masonry Design Programs is proud to announce the official release of Masonry Analysis Structural Systems (MASSTM) Version 3.0.
Major Changes in MASS™ Version 3.0
The major changes are listed below while the full list of changes can be found on the MASS website here as well as in Section 1.6 of the MASS help files.
Design Codes and Standards
As mentioned above, Version 3.0 adapts all masonry design procedures from Version 2.2 to using current design standards. Two papers outlining these changes were published and presented by Dr. Drysdale, Dr. Banting, and David Stubbs at the recent 13th Canadian Masonry Symposium hosted by the Canada Masonry Design Centre (CMDC) and Dalhousie University. These papers can be found here (Part 1: Non-Seismic Changes) and here (Part 2: Seismic Changes). With the exception of seismic minimum reinforcement requirements, all of the changes within the current scope of MASS are considered non-seismic. The next release of MASS which is already in development will increase this scope to include higher levels of ductility performance, as well as the rest of the newly added CSA S304-14 Chapter 16: Special Provisions for Seismic Design.
New Project File Format
In an effort to reduce confusion around which projects have been designed in accordance with which codes and standards, the project file format “.masonry14” was created which designs exclusively to the current standards. MASS Version 3.0 can still open old projects, however upon opening them, you will be prompted to “Save As” a “.masonry14” project as the design results may be affected. An article explaining the difference and compatibility can be found online here.
Additional Bug Fixes
As software issues are discovered, they are posted on our “Known Bugs” page which is linked from the MASS website homepage and kept up to date. There was one bug recently discovered internally at the CMDC what was also present in Version 2.2 which was re-compiled at MASS Version 2.2.1 and included in the Version 3.0 download. An explanation of the bug can be found here and a Version 2.2.1 explanation can be found here.
