Purely compressed shells are often elegant and highly efficient structural forms, but this leanness may create risk if they subjected to unexpected patterns magnitudes of loading, such as arise due seismic events. In the same way that historic masonry structures were designed sustain loads by activating purely compressive force paths, a modern metamaterial can be for specific purposes following logic. Conventional analysis methods compression-only vaults, developed structures, have tended not model combined vertical horizontal directly. This has created significant challenge engineers assessing vaults or designing new shells. To address gap, paper presents an enhanced method based on membrane equilibrium (MEA) static theorem limit analysis. approach is first application MEA directly consider body forces acting shell through parametric formulation Airy stress function. The applied case study sail vault loads. Moreover, it demonstrated how used define iso-resistant shapes offer more sustainable design options while preserving capacity.
