A parameter U^*, which is independent of stress and strain, has been introduced by the authors for expressing load transfer and load paths in a given structure. The conventional U^* is defined by the energy caused by displacement at the loading point. Since it is necessary to constrain an arbitrary point during the estimation of U^*, the value of U^* cannot be calculated for a point under distributed displacement. Hence, to overcome this difficulty, a new parameter U^<**> has been developed in our study. The parameter U^<**> is defined by the complementary energy caused by force at the loading point. A mathematical formulation with complementary energy and stiffness matrices is demonstrated, which can be used for rapid and efficient computation of U^<**>. The parameter U^<**> is used for expressing load transfer in the case of a reinforced rectangular plate under the condition of out-of-plane distributed loading.
