The article deals with the study of the dynamic characteristics of the building frame by finite element method, using the method of regulating the stiffness of the system. The spectrum of frequencies and forms of natural vibrations of the building frame is obtained. The pulsation component of the wind load on the two main axes of the building is determined and a static calculation is made taking into account this load. Different variants of the frame modeling differed in the thickness of floor

Variation of the geometric characteristics of the elements of the frame of the building allowed to choose the best option of the design scheme. The level of dynamic comfort is estimated by the results of the analysis of acceleration of the upper floor of the frame.
