The paper present solve the problem of effect the normal force from own weight on the bending amplitude of the high construction. Given the results of transverse oscillations of constructions with height of 200 meters in the resonance region and the beating. The load of its own weight changing from zero at top point of the construction to maximum value at the bottom point.

This problem is important from practical side of view, especially with the expansion of the high construction.

Found that when the frequency disturbing force with a frequency of natural oscillations of constructions without regard N observed resonance, and given N the beating.

The paper presents solution of the problem on effect of the axial dead weight force on bending frequency of high-rise structures. This force changes from zero in the top point to the maximum value in the rigid support.

This problem has practical significance in view of large-scale high-rise construction.

The paper shows that for structures 200?250 m high and more one should consider the effect of N on free frequency.
