The paper presents analytical determination methodology of fire-resistance limits of reinforced concrete slabs and wall panels. That flat multilayered structural elements could, also be parts of three-dimensional modules of building. The developed calculation method of fire-resistance limits makes it possible to determine the temperature distribution within the body of a structural element, and to define the actual stress-strain state of a structural element. The numerical-analytical method is used for calculations. Bubnov-Galyorkin method is used in two directions and differential character of the calculation retained in the perpendicular to the plate direction. Thus, an approach has been developed which makes it possible to evaluate fire-resistance of single- and multilayered flat structures by means of analytical determination; the three dimensional strain capacity character of structures are taken into consideration.
