DEFINING FIRE AND TECHNICAL CHARACTERISTICS OF A STEEL BEAM WITH CORRUGATED WEB AND ITS COMPLEX LINING
This new technical solution introduced in the paper is related to the area of fi re safety and involves the method of determining required indicators of constructional fi re-proof characteristics of a steel beam with corrugated web which in itself is a composite welded I-beam with large sheet and plate lining. The paper also delivers results of patent research on the problem of steel constructions fi re protection and describes other similar technical solutions. The authors analyze shortcomings of these solutions and their technical level, identify tasks and objectives of their new technical solution and demonstrate technical eff ects of the new technology (such as devices, inventions, utility models). Further in the paper activities and measures to achieve the proper technological eff ect are outlined and application peculiarities of fi re and technical characteristics of the integrated steel lining are indicated. The researchers also stress specifi cs of the I-beam components performance evaluation and put forward new analytical equations to calculate fi re resistance characteristics of steel elements as well as a new methodology for determining geometric and heat-technical characteristics of complex fi re-proof lining. There is also an example of calculations according the developed algorithm given in the paper.
