✦ Synopsis

This paper describes a new technique for the limit state analysis of arcuate masonry vaults. The technique involves modelling the principal stresses in a masonry vault as a discrete network of forces. This network of forces is constrained to lie within the masonry vault and be in equilibrium with the loads applied to the vault. Optimization techniques are used to select the optimum forces within the network and the optimum network shape. The network model can be optimized to calculate either the geometric factor of safety for a set of known loads, or the collapse load factor for a given pattern of imposed loading. The application of the force network model is demonstrated by applying it to calculate the collapse load factor of a masonry barrel vault carrying a single imposed point load.
