This article provides a comparative analysis of three different regulatory documents on earthquake-resistant construction. For the calculation example and comparative analysis, the calculation of a 20-storey reinforced concrete frame building for seismic resistance according to Russian, European and American normative documents is made. A comparative analysis of the calculation results of strength and deformation characteristics is made, seismic resistance is evaluated according to the considered norms. The Pushover analysis at different spatial rigidity of the building under study was carried out, the values of the damage coefficient were obtained and compared. It is established that European and American regulations impose more stringent requirements for seismic resistance of the building than the Russian regulatory document, but due to the high safety factors and calculation algorithms at the same loads, the building calculated according to Russian standards has less seismic resistance in the calculation example. This follows from the results of the calculation of the building considered. The displacements along the x and Y axes in the case of Russian norms are more than 2 times higher. At the same time, the greatest deflections were obtained in the calculation of the European regulations, with 35% more than the maximum. Pushover analysis in the calculation of the Russian regulations showed a very small coefficient of permissible damage K1, 36% less than the minimum. After increasing the spatial stiffness of its value increased by more than 2 times and began to fully satisfy the seismic resistance. In all calculated cases, there was an increase in the coefficient K1 with an increase in the rigidity of the building, and the values themselves sought to close each other's numbers.
