Primary creep buckling of steel columns in fire
AbstractThis paper proposes an analytical method to predict the fire resistance of a pinned-pinned steel column. Traditionally, the column fire resistance is determined through the standard ISO834 fire test. Under this condition, the external load is kept constant while the member temperature rises monotonically. The complicated creep strain, as well as the degradation of steel mechanical properties is taken into account in this approach. The predictions are verified experimentally and numerically. The extensive numerical verifications show that under different external load levels and different slenderness ratios, the proposed analytical method yields accurate predictions. The procedure can be incorporated into spreadsheet application software.
