Is reviewing an alternative method to determine of seismic loads on the building of irregular structures, based on the resistance of structure to deformations of oscillation, without use of the response spectrum.  It is known that the degree of seismic effects on structures depends on the suppleness, and by decreasing their rigidity, the seismic loads are reduced. However, to ensure the strength and performance characteristics the building design is performed with the certain stiffness of structural elements, that determine the character of their oscillatory motion. This factor is used in this method for determining the seismic loads on buildings. The seismic impact is applied at the level of foundation, causing the displacement of foundations and a oscillations of the building. Corresponding external loads that could cause such oscillations, are adopted as seismic loads.
