Abstract

Purpose. To develop a methodology and conduct model fire tests of reinforced concrete columns with and without Knauf Fireboard gypsum boards structural fire protection 12.5 to 40 mm thick, to obtain a temperature distribution on the heated and unheated surfaces of the fire protection and columns, as well as on the reinforcement.

Methods. Fire testing. Thermoelectric converters temperature measurement.

Findings. A method has been developed and model fire tests of centrifuged reinforced concrete columns with and without Knauf Fireboard gypsum boards structural fire protection fire protection 12.5 to 40 mm thick have been carried out. It has been experimentally proved that Knauf Fireboard fire-resistant gypsum boards are an effective way to ensure fire protection of reinforced concrete columns, allowing to increase their fire resistance up to the standardized maximum value in the Republic of Belarus, R180.

Application field of research. The obtained results can be used in buildings and structures design process as fire resistance assessment of reinforced concrete columns protected by structural fire protection based on fire-resistant gypsum boards.
