Sekundarni naslov: Analytical and experimental studies of seismic response of an existing viaduct
Sekundarni povzetek: The purpose of this thesis was to determine the difference between tipical viaduct designed in accordance with EC8/2 and existing viaduct which is supported with I shaped pillars. That is why we designed the existing viaduct considering all demands made by EC8/2. The comparison showed that the longitudinal reinforcement between the designed and the existing viaduct is very similar. Bigger differences are preseneted in the transverse reinforcement. The amount of the transverse reinforcement is more than twice smaller than the amount, demanded by EC8/2. In addition, some details of the transverse reinforcement are unsuitable. Cyclic experimental research, that was made in cooperation with Slovenian National Building and Civil Engineering Institute, showed that the transverse reinforcement, which was used in pillars of existing viaduct, is not able to prevent the buckling of the longitudinal reinforcement bars. The response of the viaduct, designed in accordance with EC8/2, was estimated with approximative nonlinear static analysis named N2 method.

Povzetek (ePrints): Namen naloge je bil ugotoviti, kakšna je razlika med tipičnim viaduktom, projektiranim po standardu EC8/2, in obstoječim tipičnim viaduktom, podprtim s stebri I prerezov. Zato je bil obstoječi viadukt projektiran upoštevajoč vse zahteve standarda. Izkazalo se je, da je vzdolţna armatura stebrov obstoječega viadukta in tistega, projektiranega po EC8/2 podobna, prečna armatura pa se bistveno razlikuje. Količina prečne armature je več kot 2-krat manjša od tiste, ki jo zahteva standard, konstrukcijski detajli pa ravno tako niso v skladu z zahtevami standarda. Ciklična eksperimentalna preiskava, narejena v sodelovanju z Zavodom za gradbeništvo Slovenije (ZAG), je pokazala, da je prečna armatura v stebrih obstoječega viadukta pomanjkljiva, predvsem glede preprečitve uklona vzdolţnih armaturnih palic. Potresni odziv viadukta, projektiranega v skladu z EC8/2, je bil ocenjen tudi s pomočjo pribliţne nelinearne statične analize z N2 metodo. Izkazalo se je, da pri projektnem potresu lahko pričakujemo razmeroma majhno plastifikacijo stebrov v vzdolţni smeri viadukta, v prečni smeri pa le omejeno razpokanost stebrov, saj je nosilnost stebrov v prečni smeri zaradi drugih konstrukcijskih zahtev razmeroma velika.
