Modern seismic resistance theory is based on a highly simplified linear oscillator calculation model based on spectral curves, which is a simplified model. Using modern calculation complexes, it is possible to calculate buildings with an accurate calculation model (using real accelerograms), which gives more realistic results than the established seismic reliability theory. The methodology for determination of reaction spectrum for simple span composite steel and concrete beam superstructure with a length L = 42.6 m on real earthquake records (accelerograms) is discussed. The methodology for selecting accelerometers is based on the criterion of selecting an accelerogram (or group of them) that determines the development of maximum forces in superstructure. The periods and frequencies of the own oscillation of the simple span composite steel and concrete beam superstructure were determined, on the basis of which the vertical compiler of the relevant earthquake accelerometers was calculated and selected. For the construction of steel-reinforced concrete slabs with different spectra obtained for different categories of soil and also according to various normative documents (GEO, SNiP, EN and AASHTO) we calculated the slab construction, compared the results and analyzed them. Based on them, the recommendations for the national annex to the Eurocode normative document were defined.
