This article presents the results of evaluating the seismic resistance of high-rise buildings on real records of the accelogram and on regulatory documents using the LIRA-SAPR SP. The maximum and minimum values of bending moments, longitudinal forces, shear stresses are determined, and the most vulnerable areas where cracking in load-bearing structures is possible are determined. It was found that the values of force factors arising in buildings under the action of the accelogram turned out to be 2 times less than the values obtained from the data based on regulatory documents. Along with this, it was found that the results of the calculation for the seismic resistance of high-rise buildings according to real accelerograms and according to regulatory documents showed that the higher the building, the greater the magnitude of displacements, bending moments and longitudinal forces on the upper floors of buildings. This requires the development of appropriate measures to reduce the vibrations of the upper floors of multi-story buildings.
