Probability Analysis of a Composite Steel and Concrete Column Loaded by Fire

Paper deals with the assessment of the fire safety of composite steel and concrete column as the selected structural element of 30 storey building. The effects of the fire are considered in accordance with the standard EN 1994-1-2. The probability of the column collapse is calculated. The deterministic and probability analysis of the fire resistance of the composite column is considered. The MC simulation is realized for 106 samples of the input data. The sensitivity analysis of the various input parameters shows the significant influence of the action effect and material uncertainties.
