Design of liquid-storage tanks: results of software modeling vs calculations according to Eurocode : Master's Thesis

Cilj ovog diplomskog rada je prikazati i objasniti postupak proračuna spremnika za tekućine prema Eurokodu te takve rezultate dobivene analitički usporediti s rezultatima računalnog modela. Primjer na kojem je napravljena usporedba je nadzemni čelični spremnik za vodu, sa stjenkom promjenjive debljine i ukrutnim prstenom na vrhu. Prvo je ukratko objašnjena teorija ljuski i membransko stanje naprezanja, opisani su opći pojmovi i dijelovi vertikalnih nadzemnih spremnika. Treće, opisan je zadani predmetni spremnik. Četvrto, napravljena je detaljna analiza plašta spremnika prema Eurokodu. Analiza MKE je odrađena pomoću programskog paketa Scia 17.01. Na kraju su tablično prikazani i uspoređeni svi rezultati.The objective of this thesis is to show and explain the design process of liquid storage tank according to Eurocode and compare results obtained analytically with software analysis results. Calculations were done on an aboveground vertical steel water storage tank with variable thickness wall and stiffening ring on top. First, shell and membrane stress theories are briefly explained, and descriptions of general terms and parts of vertical above ground tanks are given. Third, the given tank is described. Fourth, a thorough analysis of tank wall according to the Eurocodes was shown. The FEM analysis was performed using Scia 17.01 software package. Finally, all the results are presented in the tables and compared
