The paper presents a new resource-saving methodology of determining design fire resistance of composite (steel reinforced-concrete) building constructions. The suggested methodology establishes indicators of fire safety of a building which consist in ensured duration of a steel corrugated wall resistance and of tension and compression composite flange of reinforced concrete building structure in terms of standard heating tests; as well as in the assessment of designed limits of fire resistance of a composite building structure during its design-stage, construction or maintenance of the building; and also in for of fire resistance. The paper introduces an improved algorithm for solving fire-technical tasks in respect to express-calculation of designed fire resistance of composite building structures. The article provides results of a scientific research and the content of its technical effect including resource saving while putting into practice an innovative solution of fire protection and ensure fire-resistance of buildings constructions. The results of this scientific research are recommended for practical application in design organizations and can be used to improve existing regulatory documents for fire safety.
