Bug Notification: Non-Seismic Lateral Companion Loads Amplified for Seismic Effects
Be aware of this for shear wall designs resisting lateral earth pressures
In cases where a bug or other issue is found in th...
Version 4.0 Feature Spotlight: Simplified National Building Code Seismic Design
Added to the 2015 National Building Code of Canada is a new design pathway that can be used for areas with very low seismic hazard leve...
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...
Why ISN’T the Factored Shear Force Scaled up for a Seismic Design?
While you might not have expected it, MASS has it's reasons for leaving your factored shear alone - even with earthquake loads applied
...
Bonus Post: What happens when you treat a Multi-Storey Design as an Element when Increasing Factored in-Plane Shear ?
Does changing the analysis method effect the final results?
The process shown here is how MASS internally performs the analy...
Checking Vf,seismic for a Shear Wall Element
Taking seismic effects into account in MASS can be confusing. Seeing factored shear forces scaled up by over 100% in some cases may see...
