UDK: 621.642:624.014.044 DOI: 10.14415/JFCE-881 CC-BY-SA 4.0 license Summary: This paper presents a calculation of a steel vertical water tank, with a total height of 19,2 m and a diameter of 8,59 m. The construction of this tank was modelled using the ABAQUS software package, whereby a realistic picture of the stress notations in the walls of the tank was obtained. The structural load analysis was performed based on European and American standards, as well as comparison of the obtained results. Keywords: Steel tanks, EuroCode, API 650, FEM 1. INTRODUCTION Tanks are very important components of industrial and agricultural facilities, because they serve to store various liquids (water, wine, petroleum, oil, etc.) The type of tank depends on geometrical and structural characteristics, capacity, material from which they are made, a place and a method of installation, characteristics of the liquid to be stored, and its application. The basic classification of the tanks is based on their position in relation to the ground, therefore they are divided into elevated and underground Rezime: U radu je prikazan proračun čeličnog vertikalnog rezervoara za vodu, ukupne visine 19,2 m i prečnika 8,59 m. Konstrukcija rezervoara je modelirana pomoću programskog paketa ABAQUS, pri čemu je dobijena realna slika naponskih stanja u zidovima rezervoara. Analiza opterećenja konstrukcije je izvršena na osnovu evropskih i američkih standarda, kao i poređenje dobijenih rezultata. Ključne reči: Čelični rezervoar, Evrokod, API 650, MKE 1. UVOD Rezervoari su veoma važne komponente industrijskih i poljoprivrednih objekata, jer služe za skladištenje raznih tečnosti (voda, vino, nafta, ulje itd.). Tip rezervoara zavisi od geometrijskih i konstruktivnih karakteristika, kapaciteta, materijala od koga su napravljeni, mesta i načina ugradnje, karakteristika tečnosti koja se skladišti i primene. Osnovna podela rezervoara je prema njihovom položaju u odnosu na tlo. Prema tome se dele na nadzemne i podzemne rezervoare. Najčešće se izrađuju u obliku cilindra, 1 Prof. dr Miroslav T.
