| 内容記述 | This dissertation presents a multi-scale framework for stress-responsive optimization of spatial Voronoi shell structures in architecture, integrating topology optimization, genetic algorithms, and environmental risk assessment to enhance sustainability and performance. Motivated by the intersection of computational geometry, recycled materials, and additive manufacturing, the research addresses inefficiencies in traditional structural design by developing adaptive Voronoi tessellations that respond to stress fields while minimizing material use.The methodology encompasses macro-scale form-finding via SIMP topology optimization and Voronoi generation, meso-scale refinement through Lloyd relaxation and multi-objective genetic algorithms, and micro-scale validation using finite element analysis on 20 design variants. Environmental impacts are quantified through life-cycle assessment augmented by a Bayesian risk framework, accounting for innovation uncertainties in recycled PLA fabrication.Results demonstrate up to 40% material reduction with maintained structural integrity, superior stiffness-to-weight ratios, and reduced carbon footprints compared to conventional designs. This work advances computational architecture by reconciling performance optimization, digital fabrication feasibility, and environmental ethics, offering practical guidelines for sustainable built environments. | |||||||
