Way of Simulating of Seismic Impacts on Building and Structures

Abstract

The article includes the method of simulating of seismic impact to structures by system of vibration directional machines. Essence of the method concludes in reproducing of powerful vibrating machines in the different stores of the structure where oscillation characteristics are selected based on the spectrum of acceleration of the earthquake and so that the values of the inertial forces arising in the structure during their operation are equal to the true values of seismic forces which arise during the same earthquake. The offered method gives an opportunity for modeling of the stress-strain stain of the structure is taking place during the earthquakes without moving its foundation.

Экспериментальное Исследование Динамических Характеристик Точечно Опертых Квадратных Плит

“…Следовательно, для динамических и сейсмических расчетов точечно опертых плит, применяемых в конструкциях зданий и сооружений, практический интерес представляет определение их динамических характеристик, частот, форм собственных колебаний и декремента затухания. Теоретические исследования этой задачи обычно производятся по приближенным методам расчета [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

“…Consequently, for dynamic and seismic calculations of point-supported slabs used in the structures of buildings and structures, it is of practical interest to determine their dynamic characteristics, frequencies, forms of natural vibrations and damping decrement. Theoretical studies of this problem are usually carried out using approximate methods of calculation [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”
