The invention belongs to the technical field of civil engineering, and relates to a wide combination-hybrid beam cable-stayed bridge joint section test model design method, which comprises the following steps of: determining a maximum stress area on a total cross section in a joint section range as a local cross section model according to a finite element calculation result; according to a finite element calculation result, obtaining a local section model loading internal force by using a local section model internal unit node force integration method; selecting the geometric similarity ratio of the model under the principle of considering the test loading capacity and reducing the model processing difficulty; determining the design and arrangement of a shear connector according to the principle that the slippage of the interface of the steel structure and the concrete structure obeys the similarity principle; according to the method, the test model is designed in the mode that the local section of the origin
