“…Works [5,6] report the results of studies into modern theories of seismic resistance, as well as a procedure for calculating buildings for seismic impacts. It is shown that the theory of seismic resistance should take into consideration the wave nature of the seismic movement of the soil, namely:…”

This paper considers the issue related to the protection of buildings and structures against seismic influences and the prevention, exclusion, or reduction of seismic hazards. The catastrophic destruction of modern «earthquake-resistant» buildings in Turkey and Taiwan has shown that existing methods of strengthening and reinforcing structures are not perfect and require further study. Analysis of existing approaches to ensuring seismic resistance showed that seismic insulation and seismic suppression systems still do not have a scientific and technical justification for the effectiveness of their operation from the point of view of ensuring the stability of structures. The estimation-dynamic models of the «base-seismic insulation-structure» system developed to date do not always make it possible to simulate the joint work of their interaction during an earthquake and account for the transformation of the seismic impact on the structure. An alternative technique has been devised, a geotechnical seismic insulation screen, as a seismic insulation system that reduces the intensity of seismic loads on the structure and ensures its seismic resistance. In a specific example, the effectiveness of this seismic insulation system is confirmed. This seismic insulation technique in the form of damper screens is characterized by reliability and manufacturability in ensuring the seismic resistance of objects under construction. The results of computational and experimental modeling of the interaction of an earthquake-insulated structure with a ground base found that the values of axial forces and bending moments in a building with a seismic insulating screen are less than in a building without seismic insulation by 30‒40 %. The geotechnical seismic insulation screen makes it possible to advance the development of new seismic insulation techniques and determine their effectiveness. This technique will also be effective when strengthening the base and seismic insulation systems of historical monuments, protecting them against seismic and dynamic influences.

“…For linear response spectrum method, the resulting dynamic response are found by the rule SRSS (Square Root of the Sum of Squares). We try to determine the generalized wave model [1][2][3]15] corresponding the spectra (1)-(3). In the generalized wave model, it is assumed that translational motion X i along the i-th axis is caused by shear displacements from SH-and SV-waves and longitudinal displacements from P-waves ( Fig.…”

The article discusses the terms of the US and EU standards (ASCE -7-10, ASCE-4-98, FEMA P-1051/2016, EN 1998-6: 2005) concerning the calculations of earthquake -resistant buildings and structures taking into account wave seismic effectsin the ground base. For the considered standards, wave propagation models and accepted approaches to seismic analysis were investigated; limitations on the use of the standard methods were identified.
