Abstract
The seismoresistance of buildings and constructions is substantially connected by the regularity of the ground vibrations during the strong earthquakes. The main character of any vibration is its highness of component periods. The periods firstly depend on the environmental ground. During the strong earthquakes the precise results we can get only by a method of instrumental records. During the Spitak earthquake in 1988 with M = 7.0 in Gyumri town, which is situated 30 km far from the epicenter and had developed net of seismic stations it has been got only one record, which did not give any real imaginations about dominant periods. It’s know that many scientists and K. Kanai among came to conclusion that during the numerous earthquakes with M > 6 the main periods of grounds observed coincide with the dominant periods of micro-vibrations of the environmental grounds. Using the method of calculation of dominant periods for non-homogenous surface layers and having the micro-vibration records of Gyumri town there was defined the approximate dominant periods of Gyumri territory during the expecting strong earthquakes.

Dominant Periods of Expected Ground Motion of Gyumri Territory by a Method of Calculating Dominant Periods in Non-Homogenous Surface Layers of the Earth's Crust

The seismoresistance of buildings and constructions is substantially connected by the regularity of the ground vibrations during the strong earthquakes.
