Study of Seismic Isolation by Full-Wave Numerical Modeling

Аннотация

Seismic isolation (isolation of the foundation) is one of the methods to increase the earthquake resistance of buildings. It is shown that full-wave numerical modeling can be used for studying the efficiency of various designs of seismic isolation. We investigated how earthquake resistance of the building studied is affected by adjacent objects with contrasting elastic properties (seismic isolation of neighboring buildings, pools, lakes, rivers, caverns in the soil, ground water). It was revealed that the reliability of seismic isolation depends on the type of seismic effect. In certain cases, the presence of seismic isolation can lead to additional damage to objects.
