The invention belongs to a design method and particularly relates to an enclosed loading framework for a multidimensional bearing test on a large-scale structural member. The enclosed loading framework comprises a rigid foundation and further comprises four columns an upper cross beam, wherein the rigid foundation and the upper cross beam are respectively connected with the columns through screws to form a generally hollow cube shape, and the upper cross beam is provided with a z-direction oil cylinder. The enclosed loading framework is advantaged in that the enclosed loading framework is an internal force self-balancing system capable of improving measurement precision, multidimensional cooperation loading is further realized, and the enclosed loading framework is further equipped with multiple hydraulic oil cylinder driving systems to realize x, y and z multidimensional pulling, pressing and twisting simulation loading of a large-scale sample. For a small sample, only a pulling, pressing or twisting single condition test can be realized through a traditional design method. The enclosed loading framework can realize the cooperation loading test on a large-scale structural member under the pulling, pressing and twisting composite bearing condition.
