New criteria of stability and practical method of the spectral-wave theory of seismic stability
The new ideas presented in work lead to change of physical model of a deformable body, and according to it to addition boundary a condition of wave tasks, and also to change of a principle of superposition, at uniform and non-uniform movement of elastic ph. Changes of the deformed form of «kinetic forces», arisen in process of transition of one deformed form on another, as spasmodic changes of rigidity of one form and transition to the following form with the corresponding rigidity are established. New criteria of stability of buildings and constructions are received. The practical method of calculation on seismic stability on spectral-wave theory is developed.
