An innovation in the method of assessing the fire resistance of a reinforced concrete girderless ceiling of a building

Abstract

The article presents a new method for assessing the fire resistance of monolithic girderless non-accumulating floors of buildings and structures. The essence of the method lies in the fact that thermal (fire) tests of the floor are carried out without destruction, according to a set of single indicators of the quality of working fittings and structural concrete of continuous slabs. The use of the method makes it possible to determine the fire resistance of an uncut reinforced concrete slab of a girderless ceiling of a building without full-scale fire exposure, increases the reliability of statistical quality control and non-destructive testing, reduces economic costs.
