On line steel joist design package
This application designs open web steel joists according to the Canadian (Ontario) Building Code.
By using this software you are agreeing to our Terms of Use & Service and Privacy & Confidentiality Policies.
All joist designs must be approved by a licenced professional structural engineer in the governing jurisdiction of installation before use.
To design joists enter your email address, click design and enter your joist's characteristics. After you enter the last design the designs will be sent by email to you as PDFs.

Version
Preparing the application for a new interface built in Svelte. Other minor fixes.
Additional Loads added: Snow Pileup, Strip Load and End Moments. Other minor fixes.
Fixes to bridging calculations. Additional Loads added: Snow Pileup, End Moments, and Axial Compression.
Fixes to the handling of live load deflection and 'other' types of joists.
Updated unsupported point loads so that they are found correctly on the right side of the joist and the top chord analysis doesn't fix them in the centre of the panel. Improved top chord analysis, handling of reversal loads, etc.
Changed loads code and top chord analysis into Scala code. This allows for parallel processing speeding up the program. Added additional uniform loads and moving point loads.
Updated various JavaScript libraries and moved to Bootstrap 4. Fixed some minor bugs.
Basic first version that reliably designs a joist. Handles uniform loads and point loads.
