Abstract
Single-layer barrel vaults with one radius of curvature may be fabricated with several common grid configurations. With different configurations, the vault' s performance and aesthetics vary considerably affecting both its competitiveness and suitability for different applications. The study presented in this paper is an assessment of the most commonly adopted vault configurations and their effect on the vault stiffness/weight value, member stress distribution, number, length and weight of members, degree of statical redundancy, resistance to failure mechanisms, reliance on joint rigidity and cost. The study is parametric and covers wide variations of the vault aspect ratio, span/rise ratio and boundary conditions. The results of this study should be of significant value to the design of future barrel vault structures.
