Abstract
Single-layer barrel vaults are simple structural formations made up of a network of longitudinal, transverse and bracing members in a single layer with curvature in one direction. The configuration of the vault, or in other words the way in which the members are positioned and connected, has a major effect on the vault?s structural performance, aesthetics and cost. The study presented in this paper is intended to help designers of single-layer barrel vaults by identifying the significant differences between vaults with different configurations, and consequently determining which configuration(s) would be best in different conditions of use. The study presented is parametric and covers a wide range of several important parameters including the vault aspect ratio, boundary conditions, span/rise ratio and configuration. Through consideration of these parameters, the study presents an assessment of the effect of the vault configuration on the overall strength, strength/weight ratio, stiffness/weight ratio, overall ductility and sensitivity to local damage.
