      Because in CLT plane element don't consider the direction of Z axial. I used ACP and transform to shell element, but if i change the value of G23, the result won't be the same. but i should be the same. why? can anyone help me? thanks.

      The out-of-plane shear stiffnesses G31 and G23 are involved via shear correction factors:

      The above is taken from the Ansys documentation:
