000001850 520__ $$2eng$$aChecking analyses of large steel tanks with fluid have been carried out within the frame of the project of completion of Units 3 a 4 of the nuclear power plant Mochovce. The calculations have been carried out in accordance with the regulations NTD A.S.I. The calculations include the assessment of the tank resistance to seismic loads. The seismic analysis is based on the specified level of ground acceleration, for which the necessary floor response spectra have been generated. Problems have appeared with computation of responses of tanks with fluid. The applied ANSYS program package does not allow (for the time being) a correct response spectrum analysis with the use of FLUID30 finite elements. The application of FLUID80 elements is questionable, yet acceptable with cross-checking solution using FLUID30 elements. The paper contains procedure applied for the calculation of the convective mode frequency and the respective fluid pressure field. The resultant seismic responses of analyzed tanks have been combined with responses to static loads. Consequently, parameters of marginal seismic resistance of tanks have been computed.
