Discuss the calculations for a vertical storage tank
Thread Content
We are going to make a vertical storage tank and discuss related calculation issues. The maximum working pressure is 1.8MPa, the working temperature is 0~43℃, the design pressure is 1.98MPa, the design temperature is 50℃, the volume is 100m3, the cylinder and head material Q345R diameter and height, comprehensive consideration is taken to take the nominal diameter of 3800mm, the cylinder height of 7500mm, and the skirt support is according to GB 150 Calculation of cylinder and head thickness, opening reinforcement and safety valve seismic load, wind load and axial stress verification are to be calculated according to JB/T 4710 steel tower vessels. However, the scope of use of Article 1 of JB/T 4710 reads, "Applicable to skirt self-supporting steel tower vessels with a height greater than 10m and a ratio of height to average diameter greater than 5." According to this explanation, this storage tank is within the jurisdiction of JB/T 4710. Can the above calculations not be calculated with reference to JB/T 4710? Please give me some advice.

The calculation method in JB/4710-2005 is based on converting the tower into a rod-type mathematical model. If the height is not enough, the calculation error will be very large. Therefore, the poster's question cannot be calculated based on JB4710. From a conventional design point of view, the poster's equipment does not need to be that complicated. It can be calculated as a vertical container. Don't make it that complicated.
“"Self-supporting steel tower vessels with a height greater than 10m and a ratio of height to average diameter greater than 5". According to the conditions given by the original poster, it is obvious that the height-to-diameter ratio is less than 5.
When calculating strength and opening reinforcement, you can use ordinary vertical containers to calculate. When checking and calculating skirts, use towers to calculate. This is what I did.
I would like to ask how the original poster determined the height-to-diameter ratio? What is the main basis? What is the design of the skirt seat? I don’t know how the design of this container is going now. Can you post your design process and pictures to take a look? I’m going to encounter a container similar to this and would like to use it as a reference.
It can be designed as a vertical storage tank, not a tower.
This type of equipment is directly calculated according to the design of the vertical vessel. For the verification of the skirt, you can refer to the design of the skirt in the tower design to check the wind bending moment and overturning bending moment. As long as the verification is passed, it will be fine.
It is enough to design according to the vertical storage tank, not the tower. It is very conservative to choose skirt support. Normally, choose leg support.
This type of equipment is directly calculated according to the design of the vertical vessel. For safety, the wind bending moment and overturning moment can be checked with reference to the skirt design in the tower design. :handshake
According to the conditions given by the poster, it is just an ordinary vertical storage tank, just press JB4735.
