Buckling analysis of trapezoidally corrugated panels using spline finite strip method
AbstractBuckling of trapezoidally corrugated panels under in-plane loading is analyzed by a spline finite strip method. The influence on the elastic buckling load of various parameters, such as geometry. loading forms and boundary conditions, etc., is studied. It is found that: (1) for longitudinal compression the buckling load increases with the corrugation angle α, and for a given α the highest buckling load is achieved when the ‘proportion parameter’ ; (2) for shear loading the buckling load increases as α increases, and for a given α the highest buckling load is obtained when ; and (3) for a combined loading of compression and shear, interactive curves can be approximated by unit circles when . However, when a parabola seems to be a better approximation. Based on the numerical experiments, simplified formulae and interactive curves are suggested for practical design.
