Sizer 2020 (Version 11.0) was released on December 23, 2020. The major features implemented with this version were
Update of the CSA O86 design Standard to the 2019 edition from the 2014 edition. It is still possible to design with O86-14 or O86-09.
Implementation of allowable vibration-controlled joist spans, from O86 A.5.4.5 for any material and for I-joists also the method from 1997 CWC/CCMC Concluding Report, Development of Design Procedures for Vibration Controlled Spans using Engineered Wood Members
Implementation of rigorous rigorous shear deflection calculations based on Timoshenko beam theory, which has been incorporated in our matrix stiffness loads analysis engine. Shear deflection is calculated for CLT, I-joist and SCL members; it is not required for sawn lumber or glulam.
Generating a table of maximum allowable spans for a given loading and beam or joist configuration. Note that this is currently considered a "Beta" feature as it has not yet been rigorously tested for all member types and materials
