Abstract

This article focuses on a geometric optimization method for geodesic lattice domes that maintains the initial dome’s external shape and grid pattern symmetry while significantly reducing computational complexity. Using a precise mathematical expression, the study optimized 64 geodesic domes across six objective functions, comparing results with a previous method that allowed nodal movement on a spherical surface but required much higher computational effort. The findings show that for objective functions related to the standard deviation of member length and minimum buckling safety factor, the new method produces mechanically and geometrically similar optimal domes with 10 to 100 times fewer iterations. This approach enables effective optimization of lattice domes while preserving their intended aesthetic and functional design features.
