Conventional Construction Comprehensive Analysis Example
Are you curious about how MASS conducts a detailed analysis of Conventional Construction walls through its Comprehensive Analysis metho...
Change Notification: Axial Load Limit for Conventional Construction Walls
The axial load limit for a Conventional Construction shear wall with a seismic hazard exceeding 0.35, currently in MASS, complicates th...
Deflection Check for Out-of-Plane Walls
When designing out-of-plane cantilever walls subjected to lateral loads, the MASS software can be used to check the wall’s deflection a...
Change Notification: Lambda Values for Beam Density and Shear
Deviating from the CSA Standards to better reflect practical design
While the existing implementation for MASS Versions 3.0 ...
Bug Notification: Drift Values instead of Elastic Deflections used for Inelastic Rotational Demand
The current MASS approach in Version 4.0 means that linear elastic deflections are over-corrected in a way that largely overestimates d...
Bug Notification: Seismic reinforcement spacings applied to all shear walls resisting an earthquake load
While most seismic requirements are triggered by the application of an earthquake load, MASS is too stringent on it's reinforcement spa...
Bug Notification: Out-of-Plane Shear Resistance checked only at location of maximum shear
While not always calculated at the critical location of a wall, out-of-plane walls are typically governed by flexure.
In cas...
Why doesn’t MASS consider Type 6 Structural Irregularities?
With MASS Version 4.0 moving into Multi-Storey Shear Wall design, why doesn't the software check for something that seems squarely with...
Failed the Ductility Verification? How to Pick a Higher εmu, the Maximum Compressive Strain
The addition of boundary elements to MASS Version 4 (as well as CSA S304-14) means that failing a ductility verification is not the end...
