IN-PLANE INELASTIC BUCKLING AND STRENGTHS OF STEEL ARCHES

The authors of this technical paper study the in-plane inelastic buckling and strengths of circular steel I-section arches using a finite-element program for the nonlinear inelastic analysis. To determine the elastic-plastic-strain-hardening behavior of the arches, the effects of the arch curvature, large deformations, high-order deformed curvatures, material inelasticity, initial crookedness, and residual stresses are considered. Radial loads uniformly distributed around the arch axis, concentrated loads, and loads distributed along the horizontal projection of the arch are examined, which leads to uniform compression or combined bending and compression in the arch. The authors also examine the effects of initial crookedness, rise-to-span ratio, residual stresses, and dead load to total load ratio on the in-plane inelastic stability and strengths of steel arches in uniform compression and in combined compression and bending.
