I am trying to get linearised stresses in a combination of solutions where one of the load cases is a response spectrum and I don't get the linearised stress option. On the other hand, if I remove the response spectrum load case, it allows me to get linearised stresses. Any idea or option that could solve the problem? Thank you very much!!

Linearized stresse are not supported for Response Specturm results.

I don't think linearized stress makes sense in a response spectrum result. The response spectrum result is arrived at by squaring mode shapes; adding them up and taking the square root. So all the signs are lost for the component stresses. So this cannot be split into membrane and bending stresses.
