Incremental dynamic analysis of RC framed building

U okviru diplomskog rada provedena je inkrementalna dinamička analiza triju okvirnih AB prostornih modela koji se razlikuju prema obliku konstrukcije. Model A je osnovni referentni te je u potpunosti simetričan i u tlorisu i u pogledu, model S predstavlja konstruktivni sustav koji je simetričan oko srednje osi u pogledu, a model N konstruktivni sustav koji je nesimetričan. Svi modeli su modelirani kao nelinearni pri čemu su u obzir obuhvaćene nelinearnosti modela materijala te plastičnosti elemenata. Modeli su opterećeni skupinama zapisa potresa definiranih spektrom odgovora na osnovu maksimalnih ubrzanja tla: 0,1 g, 0,2 g i 0,3 g. Provedena je inkrementalna dinamička analiza, definirane su IDA krivulje, krivulje oštetljivosti te procjenjene vjerojatnosti otkazivanja nosivosti i oštetljivosti konstrukcije u ovisnosti o vrijednostima međukatnih pomaka. Napravljena je usporedba rezultata te su dani zaključci i prijedlozi primjene nelinearnih modela.Within the master’s thesis, an incremental dynamic analysis was preformed for three framework RC spatial models that differ according to the shape of the structure. Model A is the basic reference and is completely symmetrical both in floor plan and in view, model S is a structural system that is symmetrical about the middle axis in view, and model N is a structural system that is asymmetrical. All models were modeled as nonlinear, taking into account the nonlinearities of the material model and the plasticity of the elements. The models are loaded with groups of seismic records defined by the response spectrum based on maximum soil accelerations: 0.1 g, 0.2 g and 0.3 g. Incremental dynamic analysis was performed, IDA curves, vulnerability curves were defined, and the probabilities of bearing failure and structural damage were estimated depending on the values of interstory drift ratios. A comparison of the results is made and conclusions and suggestions for the application of nonlinear models are given
