Secondary title: Numerical analiysis of timber - concrete composite beams considering inter - layer slip and delamination
Secondary abstract: A new numerical model for the non-linear analysis of two-layer timber-concrete composite beams is presented. Numerical model is based on a strain finite element method. The effect of slip and uplift at the contact interface is considered for determination of stress-strain state of a two-layer composite beam which is an important novelty of presented model. Planar geometrically linear Reissner beam model and non-linear constitutive law of timber, concrete, steel and interface connection in longitudinal and transverse direction is considered. An excellent agreement between experimental and numerical results is observed. Therefore, it can be concluded that presented model is suitable for the analysis of two-layer composite timber-concrete beams.

Abstract (ePrints): V diplomski nalogi je predstavljen nov numerični model za nelinearno analizo dvoslojnih kompozitnih nosilcev iz lesa in betona. Numerični model je zasnovan na deformacijski metodi končnih elementov. Pomembna novost predstavljenega modela je v tem, da je za določitev napetostnega in deformacijskega stanja dvoslojnih kompozitnih nosilcev mogoče upoštevati tudi vpliv zamikov in razmikov na stiku med lesenim nosilcem in armiranobetonsko ploščo. Pri izpeljavi modela je bil uporabljen geometrijsko linearen Reissnerjev model ravninskega nosilca in nelinearni konstitucijski modeli lesa, betona, jekla in stika med slojema v vzdolžni in prečni smeri. S primerjavo med eksperimentalnimi in numeričnimi rezultati je bilo ugotovljeno, da je model zelo natančen in zato primeren za analizo dvoslojnih kompozitnih nosilcev iz lesa in betona.
