Study of Thermal Exposure of a Seat of Fire Inside a Building with a Façade Fabricated of Timber Materials on the Construction Elements of Adjacent Facilities

Abstract

Results of experimental determination of temperature changing of construction elements of adjacent buildings depending on heat exposure of a seat of fire involving facade fabricated of timber materials are submitted. We conducted processing of the experimental data derived. It follows from analysis of the experimental data that absolute deviations of experimental data for each experiment from appropriate average values do not exceed 12.6 ℃ that equals to 19.8% in percent expression form, and maximum root-mean-square deviation is 7.4 ℃ that indicates satisfactory convergence of the experimental data derived. We conducted check-up of belonging of the data derived to single general population by Fisher criterion and it confirmed that their dispersion was allowable. Dependency was drafted using numerical regression equation of the building facade surface temperature on the separation distance between such a building and seat of fire and duration of heat exposure. We showed that divergence between calculated data derived using this dependency and experimental data did not exceed 20%, and this is acceptable for further application of the results derived. Dependency of change of the temperature decrease factor on the separation distance to the heat source was determined which was of non-linear nature.
