      다국어 초록 (Multilingual Abstract)

      In this paper, a new structural optimization method, “percentage structure optimization”, is presented. This method is obtained by using fi nite element method (FEM) to reduce a specifi c proportion of the stress ineffi cient element reduction, which is called the "structural optimization percentage index". In addition, an evaluation index of the optimized structure, “economic benefi t index”, is introduced. Compared with the existing structural optimization methods, the optimization process is smoother and the results are more controllable. Moreover, the method of evaluating the optimization results through the “economic benefi t index” pays more attention to the economic benefi ts of the project, and can achieve the balance between the minimization of material and the detention of bearing capacity to maximize the economic benefi ts. On the basis of the existing experiment, using ANSYS 17.0 software, two Circular Hollow Sections (CHS) X-joints are optimized by "structural optimization percentage index" of 5, 10 and 15%, and "economic benefi t index" is adopted as the judgment condition of the optimization results. The results show that the method can not only guarantee the bearing capacity, but also save materials as much as possible, and verify the reliability of the new structural optimization method.
