PROBLEM TO BE SOLVED: To provide an optimization technique for a joint position, whereby an optimum position can be obtained for a point joint or continuous joint used for joining a plurality of parts composing a structure model formed from a planar element and/or stereoscopic element.SOLUTION: An optimization analysis method for the joined position of a structure relating to the invention comprises: an analysis object part setting step in which an analysis object part in a structure model 25 is set; a joining candidate setting step in which a joining candidate 29 is set for the analysis object part; a first fixed joint setting step in which stiffness is analyzed using the joint candidate 29, thereby setting a fixed joint point 31; an optimization analysis condition setting step in which an optimization analysis condition is set; an optimization analysis step in which optimization is analyzed, thereby finding a joint point; a second fixed joint setting step in which stiffness is analyzed using the fixed joint point 31 and the joint point found in the optimization analysis step, thereby setting a fixed joint point 31; and a repetition step in which the optimization analysis step and the second fixed joint setting step are repeated a predetermined number of times or until predetermined stiffness is obtained. |
