Secondary title: Impact simulation of reinforced concrete container
Secondary abstract: In this work we present simulation of a drop of a reinforced concrete container. Analysis was done by a finite element computer code Abaqus. The type of analysis was explicit dynamics. In order to understand modeling of reinforced concrete structures in Abaqus, several tests were performed on a simple wall under shear load. In these tests the area of reinforcing bars, the distance between the bars and the position of the bars in the wall were varied. The influence of the velocity of the load on results was tested too. In the next step, impact simulations were done on a simple model of the container. This model was optimizer with respect to the numerical error. Finally, the knowledge obtained on simple tests was used to prepare a detailed model of a container, with the reinforced concrete walls modeled in a different way from its interior; the later is meant as a disposal volume for a radioactive material. By performing analyses on a detailed model, we obtained data of the level of damage of the reinforced concrete walls, which was the main goal of this work.

Abstract (ePrints): Diplomska naloga obravnava simulacijo padca armiranobetonskega zabojnika na togo podlago. Za izvedbo simulacije je bil uporabljen računalniški program Abaqus, ki izvaja analize po me- todi končnih elementov. Način analize, ki smo ga uporabili, je eksplicitna dinamika. Kako se modelira armiranobetonske konstrukcije s programom Abaqus, smo spoznali na preprostem primeru stene obremenjene s strižno silo. Izračunali smo več različnih primerov, pri katerih smo spreminjali razmak in prerez armaturnih palic ter pozicijo armature. Na teh primerih smo tudi preverili, kako na končne rezultate vpliva hitrost nanosa obtežbe. Nadalje smo pripravili preprost modela zabojnika, s katerim smo naredili prve simulacije padca. S spreminjanjem tega modela smo poskušali čimbolj zmanjšati velikosti numeričnih napak. Znanje, pridobljeno z analiziranjem stene in preprostega zabojnika, smo nato uporabili pri pripravi natančnejšega modela, kjer smo posebej modelirali zunanje armiranobetonske stene zabojnika in njegovo notranjost, kjer naj bi bil skladiščen odpaden radioaktiven material. Tako smo dobili rezultate o razširjenosti in stopnji poškodovanosti armiranobetonskih sten zabojnika po padcu, kar je bil osnovni cilj naloge.
