In general, a wooden column can be assumed as an anisotropic member that has different modulas of rigidity in the direction perpendicular to the annual ring. By taking the stress function, an anisotropic wooden column loaded by torque can be solved and compared with isotropic solution. The solution of torsional problem in isotropic has been related to the membrane analogy. Hence, the corresponding torque acting to column can be obtained by experimentation of membrane analogy. And in the case of anisotropic problems the stress acting to the column can be investigated by making a comparison between new experimental method and theory.
