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
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:
