PROBLEM TO BE SOLVED: To provide a design support device which reduces man-hour of design of rib arrangement for improving rigidity and heat resistance of a structure. SOLUTION: An information processing apparatus 1 includes: a data obtaining part 20 which accepts input of design information, physical property value information, constraint conditions of the structure, and molding conditions of ribs; and a structure analysis part 30 which performs topology optimization processing making first volume density (a) as restriction conditions using the design information, the physical property value information and the constraint conditions to extract strength required part from the structure. Data showing a position of installation to other structure is included in the design information. The structure analysis part 30 selects a rib arrangement range including the strength required part and selects installation of the rib arrangement range using the design information, further performs topology optimization processing making second volume density b (b<a) as the restriction conditions using the design information, the physical property value information and the constraint conditions, calculates density of the selected installation, and selects arrangement of the ribs using the density and the molding conditions of the ribs.
