Isotropic Modelling of CLT SAP2000

[NikolayK]

Hi Eng Tips,

This is my first time posting and happy to have joined this lovely community!

I am currently on the lookout for a method of modelling Cross Laminated Timber (CLT) as an isotropic material in SAP2000.

I have been advised there is a method of converting the orthotropic properties by modelling the CLT as an isotropic material with a reduced depth of the section in software.

I have extensively searched through literature to come across this method but cannot seem to find it.

If anyone knows of this paper/method (I believe its Austrian) are you please able to share

Also, if anyone has previously modelled CLT in SAP2000, did you go about just using the orthotropic material model?

Very grateful for any help

An isotropic material has a constant modulus of elasticity (E), you can find each of the representing thickness of a layer by equating its E to the E of the main layer, through the relationship of strain/displacement compatibility.
