Modeling and Stability Assessment of Locally Damaged Steel Columns

The stability of steel columns that have suffered localized damage is investigated through analytical and computational means. An analytical model based on the Rayleigh-Ritz technique is proposed and used to study the effect of damage extent and location on column load carrying capacity. The analytical model is run in parallel with detailed finite element models that are validated using available experimental results. Analytical and simulation results show that localized flange loss in a column could lead to a severe reduction in its axial resistance.
