Inelastic Lateral Buckling Strength and Design of Steel Arches
Arches resist general loading by a combination of axial compression and bending actions. Under these actions, an arch loaded in-plane may suddenly deflect laterally and twist out of the plane of loading and fail in a flexural-torsional buckling mode. This paper investigates the inelastic flexural-torsional buckling strength and design of steel arches under general loading using an advanced nonlinear inelastic finite element methods of analysis. It is found that the arch subtended angel significantly affects its flexural-torsional buckling strength. The effects of initial crookedness and twist and residual stresses on the strengths of arches are also investigated. Modifications of the design rules for steel beam-columns are developed for the design of steel arches under general loadings, based on the finite element analysis results.
