This depends on the settings of the design strip primarily. For each section or strip the user can choose to ignore torsion or consider is As Bending, As Shear, As Beam or per Wood Amer. Check out Help Section 51.1.20 - Torsion Considerations for details. Here's a copy, please forgive any formatting problems:
RAM Concept can consider torsion on a cross section in four different ways, depending upon the properties of the design strip segment or the design section. The four approaches are:
• Beam
• Considers torsion by designing with code beam torsion equations. (note, using the Beam option along with CSA code tells the program to check CSA section 11.3. See Section 64.6.8 Section 11.3 Shear and Torsion Tension for further details)
• As Shear
• Assumes torsion is carried entirely by varying shear across the cross-section “core” length L.
• The shear force per unit length is v = 6 T / L2
• The design shear force is Vd = V +/- 6 T / L
• As Bending
• Considers torsion by adding the torsion to the bending moment and designing bending for the combined total Md = M +/- T.
• Wood-Armer
• Refer to “Wood-Armer Torsion Design” on page 406.
• None
• Torsion is not considered in any way.
