Structural Performance of Topologically Interlocked Flat Vaults According to Joint Details

Although the notion of topological interlocking (TI) is not new, today's environment parametric design tools encourages architects and engineers to reconsider potential TI systems alternative geometries for blocks. This paper aims generate alternatives blocks by increasing contact surface area using X-joints demonstrate relationship between incrementation structural performance slab-like assemblies. A case study presented in which two flat vaults with dimensions 50 × cm were designed truncated octahedra a new geometry based on added octahedra. Each vault was subjected finite element analysis SimScale compare performances displacement von Mises stress maps. According findings, there 74.7% improvement 76.8% reduction stresses. Another conducted over seven-element system applying force centre measure results single element. Results indicated 41.7% 39% The improved demonstrated through these two-stage evaluations.
