Abstract:Magistrsko delo se ukvarja z nelinearno potisno analizo, ki je že dolgo uveljavljena metoda pri simulaciji nelinearnega obnašanja konstrukcij pri horizontalni obtežbi. Najprej so študirane in prikazane teoretične osnove programa EAVEK, ki omogoča elastično dinamično analizo konstrukcij visokogradnje. Sledi povzetek osnovnih principov poenostavljene nelinearne potisne analize spletnega programa NEAVEK. Na računskem primeru enostavne enoetažne AB stenaste konstrukcije so prikazani osnovni koraki v poenostavljeni potisni analizi in določitev potisne krivulje. V osrednjem delu magistrskega dela je analizirana 12-etažna AB stenasto-skeletna konstrukcija, ki je tlorisno zasnovana kot pravokotnik z gabariti 17,60 x 12,60 m in je locirana v Mariboru. Rezultati nelinearne potisne analize, ki so bili dobljeni s spletno verzijo programa NEAVEK, so bili preverjeni s komercialnim programom za analizo konstrukcij SAP2000. Primerjava rezultatov je pokazala, da obe analizi kažeta na podobno obnašanje konstrukcije. Na nekoliko večjo utrditev celotne konstrukcije kažejo rezultati programa SAP2000, kar pa je posledica različnih računskih modelov v obeh programih in postopnega plastificiranja posameznih konstrukcijskih elementov v okvirih in na stiku s steno, ki ga upošteva program SAP2000. Dobljeni zaključki kažejo, da poenostavljena potisna analiza s spletno verzijo programa NEAVEK, kljub poenostavitvam in nekaterim omejitvam, omogoča realen prikaz nelinearnega potresnega odziva konstrukcij visokogradnje in je zato primerno ter učinkovito orodje za modeliranje osnovnega neelastičnega obnašanja konstrukcij pri potresni obtežbi.

Title:Simplified push-over analysis of high-rise structures by using the on-line version of the NEAVEK program
Abstract:The master thesis deals with nonlinear push-over analysis, which has long been an established method for simulating the nonlinear behavior of structures under horizontal loading. First, the theoretical backgrounds of the EAVEK program, which enables an elastic dynamic analysis of building structures, are investigated and presented. In the following the basic principles of the simplified nonlinear push-over analysis of the online version of the program NEAVEK are summarized. The calculation demonstrated on a simple single-story RC wall structure shows the basic steps of a simplified push-over analysis and the determination of the push-over curve. In the central part of the master thesis a 12-story RC frame-wall structure, with typical story plan dimensions 17.6 x 12.6 metres, located in Maribor, was designed. The results of the nonlinear push-over analysis obtained with the online version of the NEAVEK program were verified with the commercial structural analysis program SAP2000. A comparison of the results reveals that both analyzes show a similar structural behavior. The results of the SAP2000 program show a somewhat larger overstrength of the overall structure, which is the result of different computational models in both programs and the gradual plastification of individual structural elements in frames and at their contacts with the wall, which is taken into account by the SAP2000 program. The obtained conclusions indicate that the simplified push-over analysis, using the online version of the NEAVEK program, despite simplifications and some limitations, allows a realistic representation of nonlinear seismic response of building structures and is therefore a suitable and effective tool for modeling the basic inelastic behavior of structures under seismic loading.
