CLT Design - PRG 360, FPInnovations Handbook, and CSA O86

Bending moment and shear design for standard CLT panels listed in APA PRG 320-19 Standard for Performance Rated CLT is in accordance with Table A2 of that document. For custom panel lay-ups and for reduced sections for fire design, the program uses the Shear Analogy Method given in the following sources

• FPInnovations CLT Handbook, 2013 Edition (referred to as CLT Handbook), Chapter 3, Structural and Chapter 8, Fire
• CSA O86-14 Engineering design in wood (the Canadian design standard, referred to as O86), Chapter 8 and Appendix A8

This Shear Analogy Method yields the results for standard sections that are shown in Table PRG 320 Table A2.

The following design procedures are taken from the NDS; further explanation is found under the corresponding NDS topics:

• Axial tension and compression design of wall panels, including an alternative calculation of lateral stability
• Combined axial and bending design of wall panels
• Bearing design
• Fire design char rates and adjustment factors.
• Adjustment factors,
• Stiffness Calculations
