Abstract

Purpose. To establish the dependences of the fire protection efficiency – the time to reach a critical temperature of 500 °C under standard fire curve – on the geometric dimensions and cross-section shapes and Knauf Fireboard fire protection thickness for vertical hot-rolled I-beams and steel pipes.

Methods. Computational models were applied interconnected with the results of Knauf Fireboard fire protection efficiency tests for vertical steel profiles of various cross-section shapes. Results. Three-dimensional computational models have been developed for simulating heat exchange with a fire gas environment for vertical steel profiles cross sections protected by Knauf Fireboard. The dependences of the Knauf Fireboard effective thermal conductivity coefficient and the volumetric heat capacity on its thickness and temperature were established. The dependences of the fire protection efficiency – the time to reach a critical temperature of 500 °C under standard fire curve – were established on the geometric dimensions and cross-section shapes and Knauf Fireboard fire protection thickness for vertical hot-rolled I-beams and steel pipes. It has been found that the warming time of steel profiles with Knauf Fireboard fire protection depends not only on the reduced to plate metal thickness (section factor), but also on the geometric dimensions and cross-section shapes.

Application field of research. The research results can be used to assess the fire resistance of steel structures with structural Knauf Fireboard fire protection.
