It is shown that the earthquake resistance of buildings during construction in difficult ground conditions has a number of features. Traditional seismic isolation systems are used without regard to the properties of weak soils and do not consider these features. New, effective design solutions are proposed that meet the requirements of improving earthquake resistance and construction in difficult ground conditions. Keywords: seismic isolation, protection devices, earthquake resistance, spatial foundation platform, sliding layer, hard pole, anti-seismic measures, flexible system. We have discussed above the methods of our ancestors to increase the seismic strength of buildings and their seismic protection. These anti-seismic measures and other seismic protection methods prove that our ancestors knew the physical nature of the impact of seismic forces on buildings and structures, as well as the law of their impact. Because these anti-seismic measures, which ensure the earthquake resistance of buildings, can be developed because of incessant research, observation, and deep analysis of experimental results for centuries, over the years, as earthquake data has been collected, the qualitative nature of this data has changed dramatically. In particular, the wide application of scientific results obtained in the field of physics to this field has opened wide opportunities for humanity in the fight against earthquakes and has further expanded the scope of their knowledge about earthquakes. A new approach to solving this problem has emerged in European science. In addition to measures aimed at increasing the load-bearing capacity of normal structures, attention has been paid to reducing the inertial forces that occur in structures during an earthquake. Measures taken in this direction are considered active measures of seismic protection of buildings. In 1925, M. M.Viscordini was the use of gula support or spherical columns with lower or upper 65
