Wood Shear Wall Calculators get an upgrade. You can now specify holdown connectors using the Simpson Strong-Tie catalog and choose between segmented or perforated shear walls.
This month, we're expanding the Wood Shear Wall Calculator's capabilities to include the ability to design perforated shear walls and specify holdown designs based on the Simpson Strong-Tie catalog. Plus, the Steel Joist Calculator is fully launched and out of the Beta version.

Let's get right into it.
We have now integrated the Simpson Strong-Tie catalog into the Wood Shear Wall Calculator to AWC SDPWS 2021 and AWC NDS 2018 so you can easily specify your holdown connectors in one place.
Holdowns are generally required when overturning conditions cause uplift at the chords. Based on the maximum chord tension load, the calculator automatically determines whether holdowns are necessary for your shear wall design.
Using the integrated member selector, you can easily choose the appropriate holdowns for your shear wall based on the complete Simpson Strong-Tie catalog, removing the need to refer to or browse the catalog and manually calculate the holdown capacity.
You now have the option to choose between perforated or segmented shear wall types when designing shear walls with the Wood Shear Wall Calculator.
Plus, when creating perforated multi-story shear walls, you have the ability to include openings at any location of any story in your design. This added flexibility saves you time by eliminating the need for manual load calculations from one story to another.
The key difference in these wall types is in how openings are considered in the shear wall capacity calculation.
Perforated shear walls offer greater architectural flexibility because of continuous openings within the walls. Additionally, perforated shear walls typically only need holdowns at the very ends of the shear walls compared to every opening in segmented shear walls, making it more cost-efficient and less labor-intensive to construct.
The calculator will also automatically determine the holdowns required for your shear wall design based on whether the shear wall is segmented and perforated, and you can also now easily determine your holdown specifications with the latest integration of Simpson Strong-Tie connectors database in the calculator.
The Steel Joist Calculator to SJI 100-2020 has been extensively and independently reviewed by an external reviewer and is now out of its Beta version.
In summary, the Steel Joist Calculator allows you to:
