Eurocode 3 - Design of steel structures - Part 4-2: Tanks

pending
Organization: CEN
Publication Date: 1 August 2016
Status: pending
Page Count: 15
ICS Code (Stationary containers and tanks): 23.020.10
ICS Code (Metal structures): 91.080.10
ICS Code (Technical aspects): 91.010.30
scope:

"(1) Part 4-2 of Eurocode 3 provides principles and application rules for the structural design of vertical cylindrical, conical and pedestal above ground steel tanks for the storage of liquid products with the following characteristics:

a) tanks with capacity greater than 100 m3 (100 000 litres);

b) tanks that have significant fabrication or assembly on site;

c) shop-fabricated tanks with conical bottoms, supported on skirts or columns;

d) tanks with characteristic internal pressures above the liquid surface not more negative than −0,1 bar and not greater than 0,5 bar1);

e) design metal temperatures limited to the ranges:

1) tanks constructed using structural steel grades, −50°C < T < +300°C;

2) tanks constructed using austenitic stainless steels, −165°C < T < +300°C;

3) tanks constructed with special steel grades that have defined yield strengths up to higher temperatures, −165°C < T < the maximum defined temperature for the grade;

4) tanks susceptible to failure by fatigue, T < 150°C;

f) in cylindrical ground-supported tanks, the maximum design liquid level not higher than the top of the cylindrical shell.".

8) This Part 4-2 does not cover:

- tanks of rectangular planform;

- tanks with capacity below 100 m3;

- tanks exposed to fire (refer to EN 1993-1-2);

- tanks with dished ends and diameter less than 5 m;

- cylindrical tanks with an aspect ratio of height to diameter greater than 3.".
