In this article, we study the numerical solution of the equations of motion of seismic-dynamic problems of complex knots of underground structures containing the Duhamel integral using the trapezoid and Simpson methods. To obtain numerical results, single seismic pulses and tabulated accelerogram values of the devastating Gazli earthquake are used. Investigation of the voltage and displacement, side pipes relative to the ground in the vicinity of complex nodes. Important conclusions have been made regarding the seismic resistance of complex assemblies and side pipes during earthquakes.
