| Abstract |
This study presents the structural optimization technique of double-layer space frame structure according to the lattice division and height variation. First, the automated computation of joint coordinates and numbering technique are considered for the shape modeling. Also, the objective function for optimization is expressed as the whole member weight of double-layer space frame. Specifically, the member resizing technique and the design variable linking technique for member grouping are developed in the optimization process. Finally, the optimal design formulation and algorithm through the sensitivity analysis technique are presented to select the optimal alternative of double-layer space frame structure. |
