Video tutorial on calculation of cylindrical vertical steel reservoirs with liquid on seismic action has been posted on our channel. The main aspects and problems of the calculation of such objects are covered. Also an example of calculation in SP LIRA 10.12 of a typical liquid tank according to some criteria of strength and stability is shown, considering recommendations of EN 1998-4: Eurocode 8 and acceleration response spectra as an incoming seismic action. This video is in Russian.
