Calculations

Welcome to Catalogue Calculations, a growing library of representative example buildings developed using the Part 9 Bracing Calculator.

Throughout these examples, Part 9 lateral bracing design is approached using a simple four-step Design Process:

Conceptualize the Braced Storeys and Band Layout
Calculate the Required Bracing Length
Locate the Required Bracing Length on the Band Layout
Iterate the design

The examples presented here have been developed using this same methodology, demonstrating a practical, repeatable approach to Part 9 lateral bracing -— from interpreting the architectural drawings through to the completed calculations.

Each example includes:

Marked-up PDF plans
Editable calculation worksheets — customize for your location and construction preferences!
Video walkthroughs (coming soon)
