Stress-strain state of composite reinforced concrete slab elements under fire activity

One of the most topical issues (in construction) has become providing fire protection facilities for reinforced concrete. The Eurocode-4 and other recommendations have been applied for more than 10 years in European countries. In Russia we have only one method of analysis - STO 36554501-006-2006. This work is devoted to comparise all these algorithms. 3 methods of analysis of composite reinforced concrete slab elements under fire activity are described. 3 analytical models of structures with different calculation perameters are consedered for determination of corresponding dependences and creating the algorithm of calculation. Partial coefficients were identified for analysis of composite reinforced concrete slab elements according European Standarts for application in Russian Federation. © Rybakov V.A.,Ananeva I.A.,Rodicheva A.O.,Ogidan O.T., 2017.
