The invention relates to a method for designing a primary and secondary connection section structure with uniform bias load boosting force. According to the method, at first, a solid element is used to fill the whole design area of the envelope of the structure to obtain a basic force transmission path of the structure, then an initial model of the shell model topology optimization is establishedaccording to the material distribution characteristics of the optimization results and the requirements of manufacturing process and installation distance, and the uniform constraint of boosting forceis applied in the optimization process of shell model; and then the frame-truss structure model is established by referring to the optimization results of shell model and further size optimization iscarried out, then the stiffened shell model is established according to the results of dimensional optimization and manufacturing process requirements, and further size optimization is carried out, and finally the analysis of
