Najafi R. Fire resistance of monolithic frames buildings taking into account spatial work

The calculation method of equivalent temperatures is developed. The two and three-dimensional temperature fields are certain in the areas of slab and beam. The calculation method of fire-resistance frames monolithic buildings is developed on the basis of computer technologies, with account the non-linearity physical of materials and spatial work. Conducted the features of their work found out experimental researches and validified the developed method of calculation of fire-resistance. Suggestions are developed as evaluated by bearing the capabilities of constructions and workloads in the conditions of fire allow on the basis of analysis of different scenarios of near-accidents taking into account different combinations of heating to provide the set degree of fire-resistance of buildings and constructions. The results of performances are conducted in cods and in projects planning of buildings.
