20.500.12556/RUL-107554 Računalniški pripomoček za določanje upogibnega momenta po TDR v osno obremenjenih AB elementih Computational tool for determining the bending moment according to second order theory in axially loaded reinforced concrete elements V diplomski nalogi je predstavljen računalniški pripomoček za določanje upogibnega momenta po teoriji drugega reda (v nadaljevanju TDR) v osno obremenjenih armiranobetonskih elementih v skladu s standardom SIST EN 1992-1-1. Pripomoček je izdelan v programu Microsoft Office Excel. Za izračun učinkov po TDR preprosto vpišemo osnovne potrebne vhodne podatke (geometrija, obtežba), nekatere (vrsta betona, armature itd.) pa izberemo iz seznama, pripadajoči potrebni parametri se potem samodejno vpišejo na predvidena mesta. V pripomočku se izvaja preverjanje kriterija potrebnosti upoštevanja učinkov TDR ter dve poenostavljeni metodi za določanje učinkov TDR. To sta metoda, ki temelji na nazivni togosti, ter metoda, ki temelji na nazivni ukrivljenosti. Pripomoček nam na koncu vrne vrednost, za katero se poveča upogibni moment po TDR glede na upogibni moment po teoriji prvega reda. V diplomski nalogi je predstavljen še enostaven računski primer, s katerim je prikazano delovanje pripomočka. Prav tako je na koncu narejena še primerjava rezultatov. This diploma thesis presents a computational tool for determining the bending moment according to the Second-Order Theory in axially loaded reinforced concrete elements in accordance with the SIST EN 1992-1-1 standard. The tool is created in Microsoft Office Excel software. For the Second-Order Theory effect calculation we simply enter the essential required input data (geometry, load), the other data (concrete type, reinforcement, etc.) is selected from the drop-down list, and the necessary parameters are automatically entered into the designated spots. The tool tests the criterion of the effectiveness of Second-Order Theory when it is taken into consideration. There are also two simplified methods for determining the effects of the Second-Order Theory. The first is the method based on nominal rigidity, and the second is the method based on nominal curvature. At the end, the tool returns a value that increases the bending moment according to Second-Order theory against the First-Order Theory bending moment. The diploma thesis also presents an example of simple calculation showing the functioning of the tool, and the comparison of results is made in the conclusion. teorija drugega reda uklon SIST EN 1992-1-1 second order theory buckling SIST EN 1992-1-1 true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-04-26 07:45:02 2019-04-26 07:45:05 2022-08-19 03:49:57 0000-00-00 00:00:00 2019 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 134882 2992.pdf 2992.pdf 1 5EE8CE41F38A2E38D9CD4A7E1753FDF5 82faa4091e1a2c464277d90a341fdfd5fee72d567b8a0ec4f1eae81f1f16bff4 7464c837-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=118394 Fakulteta za gradbeništvo in geodezijo 0 0 0
