Abstract

Purpose. Based on experimental studies and theoretical data, to develop a methodology for assessing the fire resistance of a wide class of partitions on a steel frame using sheathing sheets of cement-reinforced plates and filling with mineral wool insulation using thermophysical characteristics obtained experimentally by calculation in a chamber electric furnace.

Methods. The methods of finite elements, parametric optimization, and experimental studies are used.

Findings. A methodology has been developed and experimental studies have been carried out on the heating of building materials in stationary and non-stationary thermal conditions. The thermophysical characteristics of cement-reinforced and mineral wool slabs at elevated temperatures for solving fire resistance problems are determined. Experimental studies have been performed to evaluate the fire resistance of a fragment of the frame partition structure using sheathing sheets of reinforced cement slabs. A calculated finite element model was developed taking into account the thermophysical characteristics of the constituent materials and the dependences of heating a wide class of partitions were obtained. An engineering methodology has been developed for assessing the fire resistance of curtain walls, taking into account the variable cross-sectional height of the rack profile, the thickness and density of the internal filler.

Application field of research. The results can be used in the development of fire-resistant solutions for structural elements of buildings, as well as for assessing the fire resistance of frame partitions in the design and construction of buildings and structures.
