Some aspects of the analysis of pile foundations behaviour under seismic action
Apstrakt
U radu su prikazani neki elementi analize šipova. Detaljnije je prikazana seizmička analiza sistema konstrukcija-šipovi-tlo, jednog 2D AB rama. Prikazana je analiza pojedinih elemenata sistema, neka moguća oštećenja za dva akcelerograma Vrančee, VR77NS i VRfoc86NS. Uticaj spektra odgovora dat je za VR77NS, jer konstrukcija tada ulazi u rezonantno područje i značajno se povećavaju oštećenja. Dati su dijagrami pomeranja, krajeva stubova tokom zemljotresa i oštećenja modela kao stanja plastičnih zglobova na kraju akcelerograma. Ukazano je na neophodnost uvođenja dinamičke interakcija sistema konstrukcija u koje je potrebno uključiti na samo šipove, već i tlo, jer to sada omogućava postignuti naučno tehnološki razvoj čovečanstva.
The paper presents a seismic analysis of the structure-pile-soil system, of a 2D RC frame. The analysis of individual system elements and some potential damage on two Vrancea accelerograms, VR77NS and VRfoc86NS are presented. The impact of the response spectra is provided for VR77NS, because the structure enters the resonant area and the damage increase considerably. Local drift diagrams during the earthquake, and the model damage featured as plastic hinges condition at the end of accelerograms are provided. It is indicated that it is necessary to introduce a dynamic interaction of the structural system, which includes not only the piles, but soil as well, because it became possible at the present level of scientific and technological progress of the human kind.
