Simple Method To Predict Fire Resistance Of Composite Columns

Myllyrnaki, J. and Baroudi, D., 2000. Simple Method To Predict Fire Resistance Of Composite Columns. Fire Safety Science 6: 879-890. doi:10.3801/IAFSS.FSS.6-879


A simplified numerical method to predict the fire resistance of concrete filled tubular composite columns is presented. The temperature analysis of the composite column is formulated as a one dimensional Galerkin FE-solution of the heat conduction equation. The simple design method of the Eurocode 4 has been applied in the calculation of the load-bearing capacity of the tubular composite columns. Calculated temperatures and load-bearing capacities are compared to the test results of concentrically loaded circular and square tubular columns filled with reinforced and non-reinforced concrete
