It is rational to discretize the microstructures that consist of thin walls like cellular solids by thin-walled structural elements such as frame or shell elements from computational viewpoint. In this context, authors tried to apply the structural elements to the micro-scale problems and pointed out the problem due to inconsistency between assumed kinematic field of the structural elements and the two-scale displacement field. In order to avoid this inconsistency, we propose the formulation that employs not the micro-scale displacement but the total ones for the freedom of micro-scale problems. Some numerical examples of linear problems show not only the advantage on the computational cost-efficiency of the present method but also the possibility of independent modeling of micro-scale problems.
