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.
