This paper introduces a new computational equilibrium analysis method for unreinforced masonry vaults, which extends Thrust Network Analysis using structural matrix analysis and efficient optimization strategies. By identifying independent states of equilibrium of funicular networks with any topology and fixed plan geometry, a robust and efficient solving algorithm is presented that allows practical limit analysis of (historic) masonry vaults with complex geometry under parallel loading conditions by fitting a provided geometrical target, e.g. the vault's mid surface. The presented framework can be seen as a strong foundation for practical equilibrium analysis of vaulted masonry.
