This is not what you wanted but I figured you should get some response.

Hire a consultant. Let the consultant convince you of their approach.

Here's what B31.3 paragraph 300(c)(3) says:
A designer capable of applying a more rigorous analysis shall have the latitude to do so; however, the approach must be documented in the engineering design and its validity accepted by the owner. The approach used shall provide details of design, construction, examination, inspection, and testing for the design conditions of para. 301, with calculations consistent with the design criteria of this Code.

It comes down to owner acceptance.
