EN Member modelling for the practical evaluation of the seismic performance of real concrete buildings on the basis of nonlinear dynamic analysis in 3D is overviewed. Fibre Element modelling is highlighted and contrasted to simplified lumped inelasticity models of members, with parameters fitted to a wealth of cyclic test results. An application to a full-scale 3-storey structure in 3D subjected to seismic testing under two horizontal components of ground motion validates this latter type of modelling. Two further applications are presented, one to explain the partial collapse of a multi-storey building in the Athens (1999) earthquake and another for the seismic assessment and retrofitting of a theatre building. The applications, which demonstrate simple lumped inelasticity member models, with parameters fitted to test results, are cost-effective and reliable alternatives to prohibitive Fibre Element modelling.
PL W artykule przedstawiono modelowanie (na bazie nieliniowej analizy dynamicznej w 3D) elementów rzeczywistych budynków betonowych, służące do praktycznej oceny wpływu oddziaływań sejsmicznych. Wyróżniono modelowanie elementami pasmowymi, w odróżnieniu od uproszczonych niesprężystych modeli skupionych elementów z parametrami dopasowanymi do dużej ilości wyników badań cyklicznych. Wykonanie trójwymiarowego, naturalnej wielkości modelu 3-kondygnacyjnej konstrukcji poddanej obciążeniu sejsmicznemu, w postaci dwóch poziomych składowych ruchu gruntu, uzasadnia zastosowanie tego drugiego typu modelowania. Przedstawiono również dwa dalsze zastosowania, pierwsze do wyjaśnienia częściowego zawalenia się wielokondygnacyjnego budynku w wyniku trzęsienia ziemi w Atenach (1999) i drugie do oceny sejsmicznej i modernizacji budynku teatru. Przedstawione zastosowania dowodzą, że proste, niesprężyste modele skupione, z parametrami dostosowanymi do wyników badań są ekonomicznie efektywne i stanowią pewną alternatywę dla modelowania elementami pasmowymi.
