Computer modelling of fire resistant solutions for structures in high-rise buildings with using of new fire-retardant materials

Abstract

The article describes possibilities of computer modeling of fire resistance for structures in high-rise buildings, which include new fire-resistant plaster compositions. As an example of program complex, “Sofistik” (Germany) was chosen for the calculation of reinforced concrete structures of tier buildings. The characteristics of fire protection compounds and their regulation, which are usually used, also are shown. According to the new code “Highrise buildings and complexes. Fire safety requirements”, limits of fire resistance for walls of not less than 240 minutes. Skyscraper “Lakhta center” with a height of 462 m and limits of fire resistance of load-bearing reinforced concrete structures 180 and 240 minutes is built up in Russia. The article investigates the means of fire protection in the business center. Moreover, modern form of cladding in Mada Residences building (Dubai, UAE) is concerned to make some conclusions about future fire resistant solutions.
