Abstract : The influence of higher-harmonic deflection components on the creep-buckling characteristics of an idealized H-section column is investigated. The creep properties of the material of the column are defined by a simple power-function creep law. Higher-harmonic deflection components reduce the column lifetime significantly only when their initial amplitudes, as well as the initial amplitude of the first harmonic component, are very large. Second-harmonic components have a much smaller effect on the column behavior than do third-harmonic components. (Author)
