This article presents the basic assumptions and calculation scheme, allowing to obtain an approximate method of calculation of the filler of three-layer structures with a sufficiently large deformability, ie structures, deflections which are comparable to the thickness of the three-layer package as a whole.

In this article, we propose a method for determining the reactive load for an element of the oval rod type with a rectangular or square cross-section, in which the diagrams of the moments of external forces and single loads are rectilinear. In this case, integration can be performed analytically

This article presents a cushioning device, as part of the system of seismic protection of buildings, in which there are no elastic elements. Described in detail the design of the device and is explained in the drawings
Keywords: seismic isolation, energy absorbing device, the shock absorbing device, the rotational movement of the torsion plastic
