What are the structural considerations for stacking cast iron elements in vertical nature forms?

Stacking cast iron elements in vertical forms requires careful attention to structural integrity and stability. Key considerations include load distribution, as cast iron's brittleness demands even weight dispersion to prevent cracking or failure. The base must be robust to support cumulative loads, while interlocking or bonding methods (e.g., mortise-and-tenon or adhesives) enhance cohesion. Thermal expansion and corrosion resistance are critical due to environmental exposure. Additionally, alignment precision ensures vertical stability, avoiding lateral stresses. Engineers must also account for seismic or wind forces in tall structures. Proper design balances aesthetic appeal with mechanical resilience, ensuring longevity and safety in architectural or industrial applications.
