Issues regarding the calculation of the bottom plate of pressure vessels at normal pressure
Thread Content
As the title suggests, this is my first time dealing with the design of rectangular containers. I am currently designing an A-type rectangular container. The NB/T 47003.1-2009 standard provides only formulas for calculating the thickness of the bottom plate and the spacing between structural members. I would like to know how to choose the size of these structural members as well as their specific type (such as channel steel or I-beam). Is any calculation required in this regard? I would appreciate some advice from someone who knows more; it’s urgent, thank you!
Type A rectangular containers with a volume of no more than 1 m3 do not require reinforcement using channel steel.
For the bottom plate of a rectangular container, the reinforcement is designed to provide only compressive strength, with no requirement for bending resistance; therefore, the value can be calculated by dividing the force by the area~
It is better to use ribs with a symmetrical cross-section due to the issue of the bending center.
