Secondary title: |
Resistance of steel beams with web openings and castellated beams |
Secondary abstract: |
In Diploma demonstration of bending and shear resistance of steel beams with openings in web and for castellated beams is being presented. Dimensioning of such beams is performed in compliance with general rules by Eurocode for dimensioning of beams by considering speciality of beams with openings or by non-linear analysis with consideration of imperfections. For delimit of beams with openings from castellated beams, geometric criteria are being used. Further approach to the dimensioning of these two types of beams depends on mentioned geometric delimitations. Resistance to lateral torsional buckling, for castellated beams and beams with openings, is demonstrated in the same way as solid web beams, by taking geometric and static characteristics of the cross-sectional area at the place opening into account. It is possible to more accurately determine the behaviour of beams with openings by using advanced computer software than by already established methods by Eurocodes. For the purpose of the Diploma a program »AceGirder« had been written, in which the user can choose from different types of beams, such as castellated beams and beams with a single or multiple openings. Software carries out a statistic analysis at a given load, analysis of the limit load and stability. |

Abstract (ePrints): |
V diplomskem delu je predstavljeno dokazovanje upogibne in striţne nosilnosti za jeklene nosilce z odprtinami v stojini in za jeklene sataste nosilce. Dimenzioniranje takih nosilcev se izvaja v skladu s splošnimi pravili Evrokoda za dimenzioniranje nosilcev z upoštevanjem posebnosti nosilcev z odprtinami ali pa z nelinearno prostorsko analizo z upoštevanjem imperfektnosti. Za razmejitev nosilcev z odprtinami od satastih nosilcev se uporabljajo geometrijski kriteriji. Od teh geometrijskih razmejitev je odvisen nadaljni pristop k dimenzioniranju nosilcev z odprtinami, oziroma satastih nosilcev. Nosilnost pri bočni zvrnitvi pri satastih nosilcih in pri nosilcih z odprtinami se dokazuje enako kot pri polnostenskih nosilcih z upoštevanjem geometrijskih in statičnih karakteristih prečnega prereza na mestu odprtine. Z uporabo naprednih računalniških programov je mogoče natančneje določiti obnašanje nosilcev z odprtinami, kot z uporabo uveljavljenih metod po Evrokodu, zato je bil za diplomsko nalogo narejen program AceGirder, v katerem je moţna izbira med satastimi nosilci, nosilci z enojno odprtino in nosilci z večimi odprtinami. S programom se dela statično analizo pri dani obteţbi, analizo mejne nosilnosti in stabilnostno analizo. |
