摘要: Abstract Steel short columns are used in building structures. The heating conditions real fires non-uniform. structural fire design approaches the Eurocode based on uniform conditions. This paper presents a numerical investigation behavior of steel subjected to localized fire. effect non-uniform condition failure temperature axially loaded is studied. Failure defined here as maximum column at (e.g. onset buckling or squashing). Simple thermal models were calculate Sequentially coupled thermal–mechanical simulations conducted. study finds that much higher than with temperature. might be slightly lower (within 20 °C) standard ISO 834 equations give conservative results for fires.
