| Popis: | Prema zahtjevima EN 1992-1-2, analize požara armiranobetonskih (RC) stupova danas se mogu izvoditi na različite načine s različitim razinama točnosti ovisno o tome koje i koliko pretpostavki (pojednostavljenja) podrazumijevaju. Danas je poznato da bi inženjeri u svakodnevnoj inženjerskoj praksi trebali težiti što većem izostavljanju ovih pojednostavljenja. Naime, zbog svoje konzervativnosti, jednostavnije metode su često više na tzv. „sigurnoj strani“ i stoga mogu dovesti do skupljih inženjerskih rješenja (npr. propisivanje pretjerane konstrukcijske protupožarne zaštite). Nažalost, do danas još nije dovoljno razjašnjeno koju bi od pretpostavki bilo najsmislenije eliminirati među prvima. Ovaj diplomski rad pokušava dati odgovor na ovo pitanje. According to requirements of EN 1992-1-2, fire analyses of reinforced concrete (RC) columns today can be performed in different ways with different levels of accuracy depending on which and how many assumptions (simplifications) they entail. It is known today that engineers in their daily engineering practice should strive for omittance of these simplifications as much as possible. Namely, because of their conservatism, the more simple methods are often more on the so-called “safe side” and thus can lead toward more expensive engineering solutions (e.g. prescribing excessive structural fire protection). Unfortunately, to date it is not yet clarified sufficiently which of the assumptions would make the most sense to be eliminated among the first. This master's thesis tries to contribute to answering this question. |
