Nonlinear seismic analisys by explicit and implicit method

Popis výsledku v původním jazyce

The paper deals with suitability of use of the explicit and implicit method in heavily nonlinear seismic analysis and also deals with comparison of response of the Drucker-Prager plastic material model and the modified Mazars damage material model to strong seismic loading. Considering typical time of duration of earthquakes from several seconds to approximately twenty seconds, it would seem that use of the implicit method is definitely more suitable. The shape of accelerograms, however, requires quite short time steps. For the explicit method, on the other hand, very short time steps are required in order to obtain a stable solution. Both methods must be compared with respect to a heavily nonlinear response, typical for seismicity. Massive yielding or damage of the material structure is achieved. Behaviour of both models under the seismic loading is fundamentally different and the paper discusses the differences. Conclusions of the paper are made on the basis of detailed numerical study and may be very useful for practice.
