The current MASS approach in Version 4.0 means that linear elastic deflections are over-corrected in a way that largely overestimates demand, making ductility verifications far more difficult. Many shear wall designs require that a ductility verification be performed and satisfied. While the software has a number of systems in Read more…
While most seismic requirements are triggered by the application of an earthquake load, MASS is too stringent on it’s reinforcement spacing requirements in cases of low seismic hazard index. When bugs are reported in MASS, they are taken very seriously. In the interest of transparency, they are also posted Read more…
The storey-by-storey design approach currently in MASS can excessively amplify shear forces beyond expected results In cases where a bug or other issue is found in the MASS software, announcements are posted on the software’s known bugs page, as well as on this page here. It is always encouraged Read more…
Be aware of this for shear wall designs resisting lateral earth pressures In cases where a bug or other issue is found in the MASS software, announcements are posted on the software’s known bugs page, as well as on this page here. It is always encouraged that suspected bugs Read more…
While not always calculated at the critical location of a wall, out-of-plane walls are typically governed by flexure. In cases where a bug or other issue is found in the MASS software, announcements are posted on the software’s known bugs page, as well as on this page here. While Read more…
Bugs are found from time to time and in our effort to be trustworthy and transparent, they are posted here as well as appearing on the MASS Welcome Screen The known bugs page has moved from the MASS website to the MASS section of the CMDC website. Click here Read more…
Understanding the issue, when it can come up, and what can be done to account for it When software bugs are found, notifications are posted in the Known Bugs page, on the MASS welcome screen, as well as here on the CMDC website software blog in an effort to be transparent Read more…
Ever had MASS stop working while working on a design? You aren’t alone! In any windows architecture application, there is a limit of 10,000 GDI objects. Internally, there a number of these crated with every design and population of each results screen. Unfortunately, there are a number of these that Read more…
Depending on keyboard or Windows system settings, it is possible to re-open a project file and see different results Have you ever saved a MASS file you were working on, only to open it up a few days later to see some values that are orders of magnitude larger? If Read more…
Understanding the issue, when it can come up, and what can be done to account for it This article originally was featured on the MASS Software Blog, formerly hosted on the software section of the Canada Masonry Design Centre website.
