20.500.12556/RUL-86026 Analiza poškodovanega rezervoarja diplomska naloga Analysis of damaged storage tank Jekleni rezervoarji so zaradi velikega razmerja med radijem in debelino sten občutljivi na stabilnost. V okviru diplomske naloge so bili preverjeni standardi za analiziranje nosilnosti in stabilnosti jeklenih rezervoarjev s poudarkom na standardu API 579 Fitness-For-Service, ki obravnava obstoječe rezervoarje. Za lupinaste konstrukcije velja, da začetne nepopolnosti pomembno vplivajo na njihovo stabilnost. Naprednejša analiza, opisana v API 579, zahteva natančen prikaz nepopolnosti, kar lahko zagotovimo z dobljenimi podatki iz laserskih skenerjev. V diplomski nalogi je bila izvedena geometrijska in materialna nelinearna analiza nosilnosti in stabilnosti obstoječega rezervoarja z uporabo podatkov, dobljenih z laserskim skenom. Naprednejša analiza je bila izvedena s programom Wolfram Mathematica in paketom znotraj programa, ki vsebuje programsko okolje končnih elementov, imenovano AceFEM. Vse analize so bile izvedene še v programu SIMULIA Abaqus FEA za kontrolo rezultatov. Due to a high ratio between the radius and wall thickness, steel storage tanks are sensitive to stability. The thesis examines the standards used in the analysis of steel storage tank strength and stability, focusing on the API 579 Fitness-For-Service standard, which deals with the existing storage tanks. The stability of shell structures is considered to be strongly influenced by initial imperfections. An advanced analysis, as described in API 579, requires an accurate representation of imperfections, which can be generated using the data obtained from laser scanners. The thesis includes a geometric and material nonlinear analysis of strength and stability of the existing storage tank conducted using the data collected from laser scanners. An advanced analysis was performed using the Wolfram Mathematica program and a package within the program that contains a finite element software environment called AceFEM. All analyses were further carried out in the SIMULIA Abaqus FEA program in order to verify the results. gradbeništvo diplomska naloga UNI stabilnost jekleni rezervoarji standardi graduation thesis civil engineering stability storage tanks standards AceFEM Abaqus wind true false false [G.
