CLT Diaphragm Moment Diagram & chord forces

[Other Aaron]

Does anyone have a good way to generate a moment diagram and chord forces for a rigid CLT diaphragm. Im looking for a system in excel that can be easily generalized, lateral supports at irregular spacings. Otherwise I'll just be conservative and use a simple span for all regular supported spans, and cantilevers where necessary.

We aren't modeling this, as it is a CLT diaphragm supported on light frame shearwalls.
