Lamella Arch

Students at SDSU DoArch split into three teams to spend a week developing a proposal with the rules of using and multiplying pre-manufactured wood pieces and something to walk under. A lamella arch structure was chosen and developed through trial and error via many built prototypes to understand the relationship between angled cuts and length of the individual lamella and how that corresponded to a larger, barrel arch radius. The term lamella refers to the underside structure of a mushroom and the structural system was developed by German Architect and Engineer, Freidrich Zollinger just after WWI. Utilizing 202 pre-cut pieces of two types, the structures are economical and lightweight while able to span long distances with no columns.
