Based on the basic principle of response spectra calculated for a single degree of freedom elastic system under horizontal seismic movement xg (t) the role of dynamic equilibrium equations were calculated using the gradient and the diff and calculate integrals using cumtrapz command accurate calculation of response spectra integral formula and simplified response spectrum integral formulas to calculate values were compared, xg (t) were selected measured vibration data explosion and natural seismic data, through calculated that more significant for high-frequency shock waves of explosions, calculated using the above method the response spectrum in the low frequency part of a small difference, is not characteristic of the overall impact of the response spectrum, but more significant for low-frequency seismic waves natural, integral formula calculated by cumtrapz integral equations with the results of calculations using the diff command to close by the results gradient calcu
