Mechanics of masonry vaults: The equilibrium …
WebThe state of a masonry arch, as of any hyperstatic structure, must conform to the equations of static equilibrium, but is determined by displacements imposed by the environment. These ‘boundary conditions' are in general unknown, but very small movements (as for example of the abutments of an arch bridge) can alter markedly the internal stresses in the … Webnot appropriate for historic structures in masonry. 1.1 Lower-bound analysis and the safe theorem Heyman (1966) introduced the safe theorem for ma-sonry structures, also known as the lower bound theorem. Put simply, a vault in unreinforced maso-nry will stand if a network of compression forces in equilibrium with the applied loads can be found over easy gil fernando
