Performance of Single Layer Steel Barrel Vault Under Buckling

Mulesh K. Pathak

Abstract :

Buckling is a critical state of stress and deformation, at which a slight disturbance causes a gross additional deformation, or perhaps a total structural failure of the part. Structural behavior of the part beyond \'buckling\' is not evident from the normal arguments of static. Buckling failures do not depend on the strength of the material, but are a function of the component dimensions & modulus of elasticity. Therefore, materials with a high strength will buckle just as quickly as low strength ones. If a structure is subject to compressive loads, then a buckling analysis may be necessary. The study presented in this paper is intended to help designers of steel aced barrel vaults by identifying the significant differences in determining which configuration(s) would be best in different conditions of use. The study presented is of parametric type and covers several other important parameters like rise to span ratio, different boundary conditions, such that barrel vault acts as an arch, as a beam or as a shell, The buckling strength of a three different configuration of a double layer aced barrel vaults are presented in this paper for rise/span ratio varying from 0.2-0.7 and having four different types of boundary conditions. Through consideration of these parameters, the paper presents an assessment of the effect of the vault configuration on the overall buckling strength.
