The simplified calculation methods proposed in EN1993-1-2 for fire design of steel columns do not take into account the restraining to its thermal elongation. In order to provide data for developing a new simplified calculation method for fire design of HEA, HEB and HEM steel columns with restrained thermal elongation a parametric study using the advanced calculation model ABAQUS, was carried out. This method was established taking into account the axial and rotational restraint to the column in case of fire, the column slenderness and the load level. The critical times and temperatures can be obtained directly from formulae.
► Simplified calculation method for fire design of thermal restrained steel columns. ► Parametric study for different values of slenderness, load levels and stiffness. ► Increasing the load level leads to a reduction of the critical temperatures. ► Increasing the slenderness leads to a reduction of the critical temperatures. ► Stiffness of the surrounding structure had not influence on critical temperatures.
